the surges

Twelve ways
through a surge.

A surge is the moment the pull arrives and your whole body agrees with it. These are twelve short, paced sequences for that moment. Each one names what it does to your body or your head, and how strong the evidence behind it honestly is.

Eleven of them run right here on this page. One of them needs you to put your shoes on and leave, and we are not going to pretend otherwise.

if this is bigger than a surge

If you are thinking about ending your life, or you are not safe where you are, stop reading this page and use one of these instead. They are answered by people, at any hour, and nothing here comes before them.

The Sigh

the body · 60-90s

Your body drops a gear inside one breath.

Two inhales stacked back to back reopen the small air sacs in your lungs that collapse when you hold yourself tight. The long exhale after them offloads carbon dioxide and slows your heart on the way out.

strong

Five minutes of this pattern beat mindfulness meditation for mood and lowered breathing rate in a randomised trial. Balban et al., Cell Reports Medicine, 2023.

“I do this in the car before I go into my parents house. Twice, three times. Nobody knows I am doing it.”four months in

The Dive

the body · 30-60s

The panic loses its grip in under a minute.

Cold on the skin above your eyes and across your cheekbones sets off a reflex your body kept from its diving ancestors. Your heart slows, blood moves to the core, and the fight-or-flight surge gets overruled by something older than your thinking.

good

Cold on the face reliably slows heart rate, and it is used as a front-line distress tolerance skill in dialectical behaviour therapy. Dive-reflex physiology; the TIP skill in DBT.

If cold is risky for you for any reason, use cool water instead of ice, or run the long exhale instead.

You need actual cold before you start. A sink, an ice pack, a cold can out of the fridge. The page can pace it. It cannot make the water cold.

“I keep a metal spoon in the freezer. Sounds stupid. It has got me through more nights than anything I paid for.”two years in

Riding the Wave

the head · 10-20 min

You watch it crest and go, without doing anything about it.

A craving behaves like a wave. It builds, peaks and falls on its own, usually well inside twenty minutes, as long as you do not feed it. Watching it from a small distance keeps the peak from turning into a decision.

good

Urge surfing comes out of Marlatt relapse-prevention work and is a core practice in mindfulness-based relapse prevention, where it has been studied in people in treatment. Marlatt relapse prevention; mindfulness-based relapse prevention trials.

“The first few times I watched the clock the whole way. Now I know roughly where the top is, and it is never as far up as it feels at the start.”eleven months in

Name It

the head · 60s

The feeling gets smaller the moment it has a name.

Putting a feeling into words moves activity away from the alarm part of the brain and back toward the part that plans and reasons. The naming itself does the work, which is why a rough word beats a perfect one.

good

Labelling an emotion reduced amygdala response and raised prefrontal activity in brain imaging work. Lieberman et al., Putting Feelings Into Words, Psychological Science, 2007.

Better said out loud. Under your breath counts.

“Nine times out of ten it is not a craving. It is that I am hungry and I have not spoken to anyone all day.”three years in

Five Things

the body · 2-3 min

You come back into the room you are actually standing in.

Threat pulls attention inward, into a loop of thought with no exit. Counting real things in the room forces attention outward, and the loop cannot keep running without your attention feeding it.

practice

This is long-standing practice in trauma and crisis work rather than a trial-tested protocol. It is here because it is used everywhere and it costs nothing, not because a study proved it. Practice-based. Widely used in crisis and trauma care.

“My counsellor made me do this in her office and I thought it was nonsense. I have used it in a supermarket car park about forty times since.”a year in

The Butterfly

the body · 2 min

The charge on the picture comes down a notch.

Slow taps alternating left and right give your attention a steady rhythm to hold while a hard image is present. The image tends to lose some of its charge and settle further back.

promising

Alternating left-right stimulation is used as a resourcing technique inside EMDR. The evidence for the tapping on its own, separated from the rest of the therapy, is early. The butterfly hug, an EMDR resourcing technique.

“I do it under a table at work with my hands on my knees. Left, right. Nobody has ever noticed.”six months in

Play It Forward

the head · 3 min

The hour after this stops being an idea and starts being a place.

Under craving the future goes flat, and something good an hour away stops counting for much. Picturing one specific future hour in real sensory detail gives it its weight back, and craving comes down with it.

good

Imagining specific future events reduces how steeply people discount future rewards, and lowers craving in laboratory work with people who use substances. Episodic future thinking and delay discounting research, Bickel and colleagues.

“I picture Sunday morning with my coffee and the paper. That specific chair. It has more pull than any of the reasons I could list.”five years in

Ten Minutes Moving

the body · 10 min

The craving comes down while you are busy doing something else.

One short bout of moderate movement changes your chemistry for the next hour, and craving intensity measurably drops with it. It also puts physical distance between you and wherever the pull is strongest.

good

Single bouts of exercise lower craving intensity across a number of trials and reviews, in tobacco and in other substances. Acute exercise and craving research.

“I hated being told to go for a walk. I still hate it. It still works every single time, which is annoying.”eight months in

This one is not something a web page can pace for you. Ten minutes, shoes on, out the door, and let the chemistry do it. Marrow will time it and remember what it did for you.

The Long Exhale

the body · 3 min

Your body takes the hint and stands down.

Your heart speeds up slightly on every breath in and slows on every breath out. Making the out-breath longer than the in-breath leans on that brake. Heart rate variability rises and arousal comes down with it.

good

Slow breathing with a lengthened exhale raises heart rate variability and lowers physiological arousal. Slow paced breathing and heart rate variability research.

“Longer out than in. That is the only thing I remembered from treatment and it turned out to be enough to start with.”two years in

Just a Thought

the head · 90s

The craving goes back to being a sentence instead of an order.

A craving arrives sounding like a command issued by you. Putting a frame in front of it, "I am having the thought that", separates the thinking from the thinker. The thought stays. Its authority does not.

good

Cognitive defusion is a core process in Acceptance and Commitment Therapy, with experimental support for reducing how believable and how gripping a distressing thought feels. Defusion within Acceptance and Commitment Therapy.

Out loud is the part that does the work. A whisper is enough.

“I am having the thought that. Six words. It puts a pane of glass between me and the thing.”a year and a half in

The If-Then

the head · 2 min

The next hard moment already has your answer inside it.

Deciding in advance takes the choice out of the moment, which is when your thinking is at its worst. A plan shaped "when X happens, I will do Y" hands the cue itself the job of setting off the move.

strong

Plans in this exact form raise follow-through substantially. Pooled across a large body of studies the effect is medium to large. Gollwitzer and Sheeran, meta-analysis of implementation intentions.

Have something to write on for the last beat. Your phone is fine.

“Mine is: when I unlock the front door, shoes off and kettle on. The old routine ran on autopilot too. This one just runs instead.”three years in

The Refusal

other people · 3 min

The words are in your mouth before you need them.

Under pressure you compose badly. Saying the real sentence out loud now, in your own voice, means the moment asks you to remember something rather than invent it.

good

Refusal skills training is a standard component of behavioural treatments for substance use, and those treatments hold up well in trials. Refusal-skills training within behavioural treatment.

You have to say the words out loud. A car, a stairwell, a bathroom. Somewhere you will not be overheard is plenty.

the labels, and what they cost us to admit

Every surge carries a label for how well the evidence behind it actually holds up. The labels are not decoration. A person deciding whether to trust this at three in the morning deserves to know which of these is trial-backed and which is simply what crisis workers have always done.

  • strongRandomised trials or meta-analysis. The finding has been tested and it held.
  • goodSolid evidence, but fewer studies, or studies in a nearby population rather than exactly yours.
  • promisingEarly, or tested only as one component inside a larger therapy rather than on its own.
  • practiceUsed everywhere in crisis and trauma work, costs nothing, and no trial has tested it. We say so rather than rounding it up.

One of the twelve carries the weakest label. It stays on the list because it helps a lot of people, and it stays labelled honestly because you should be able to tell the difference. Every claim links through to the source on our evidence page.

what works for you

A list of twelve is the easy part.

Knowing which of the twelve actually moves you, at the hour you tend to struggle, is the part nobody does. That is what Marrow is for.

Every surge you run inside Marrow can be rated twice. How loud it was before, how loud after. One tap each, zero to ten, and skipping is always fine and never mentioned again.

After three rated runs of the same surge, Marrow stops offering and starts reading. It will tell you something like this.

an example of the read, not real data

The Dive takes you down about 3 points in a minute. It is your steadiest one so far.

The Dive lands hardest in the small hours.

The Dive3.1 down · 6 runs
The Sigh2.3 down · 11 runs
Five Things1.2 down · 4 runs
The Butterflyleaves you where it found you · 3 runs

That last line is the one that matters. A tip list cannot tell you which of its tips does nothing for you. A measured one can, and it should say it plainly rather than quietly dropping it.

the questions people actually type

Plain answers.

Written to be read at the worst hour, by someone who does not have the patience for a preamble.

How do I stop a craving right now?

You do not have to stop it. You have to outlast it, and it is shorter than it feels. The fastest move for most people is a physiological sigh: breathe in through your nose, sip a second short breath in on top of it, then let a long slow breath out through your mouth. Three rounds, about a minute. It reopens the small air sacs in your lungs, offloads carbon dioxide, and brings your heart rate down inside a single breath.

If the loud part is panic rather than craving, cold water on your face will get there faster. If the loud part is your thinking, name the feeling out loud instead. All three are on this page and all three run in under two minutes.

What is urge surfing?

Urge surfing is watching a craving rise, crest and fall without acting on it. You find where it lives in your body, describe it like weather, give it a number, and keep it company instead of fighting it or feeding it. The skill is not making the wave smaller. The skill is staying in the water while it passes.

It comes out of Alan Marlatt's relapse prevention work and is a core practice in mindfulness-based relapse prevention. In one study of student smokers, brief urge surfing instructions did not lower the urges themselves, but the people who learned it smoked less over the following week. That is the honest shape of it. It changes what you do with the urge more reliably than it changes how loud the urge is.

How long does a craving last?

Most cravings crest and come down well inside twenty to thirty minutes if you do not feed them. That figure is a clinical rule of thumb rather than a measured constant, and a craving can return in waves across an evening. What is reliable is the shape rather than the number: it climbs, it peaks, it falls. It does not climb forever, even though at the peak it feels certain that it will.

Riding the Wave is built around exactly this. Ten to twenty minutes, watching, doing nothing about it, checking the number twice so you can see it move.

What is the physiological sigh, and does it help with anxiety?

It is two inhales through the nose, the second one short and stacked on top of the first, followed by a long slow exhale through the mouth. The double inhale reinflates collapsed alveoli so the long exhale can offload more carbon dioxide, and your heart rate falls on the way out.

In a randomised trial published in Cell Reports Medicine in 2023, five minutes a day of this pattern improved mood and lowered breathing rate more than mindfulness meditation over a month. That makes it one of the better-evidenced things you can do in sixty seconds. It is a way to bring your arousal down in the moment. It is not a treatment for an anxiety disorder, and it is not a substitute for one.

What should I do at 2am when I want to drink?

Two in the morning is the hour with the fewest people in it, and that is most of why it is hard. Do the sixty-second thing first and the ten-minute thing after. Start with three rounds of the physiological sigh. If your body is still loud, cold water on your face, twenty seconds. Then pick one that uses the time: the long exhale, or riding the wave.

Do not make a decision about your whole life at 2am. Make one decision about the next twenty minutes. And if the night is bigger than a craving, or you are not safe, call or text 988. It is answered at 2am.

Does cold water on the face really stop a panic spike?

Yes, and it is plumbing rather than willpower. Cold on the skin above your eyes and across your cheekbones sets off the mammalian diving reflex. Your heart slows, blood moves to your core, and the fight-or-flight surge gets overruled by something older than your thinking. Twenty seconds is usually enough. It is a front-line distress tolerance skill in dialectical behaviour therapy for this reason.

If cold is risky for you for any reason, use cool water rather than ice, or run the long exhale instead, and check with a clinician if you are not sure.

What do the evidence labels mean?

There are four and they are never rounded up. Strong means randomised trials or meta-analysis. Good means solid evidence with fewer studies, or evidence from a nearby population rather than exactly yours. Promising means early, or tested only as one part of a larger therapy rather than on its own. Practice means it is used widely in crisis and trauma work and no trial has tested it.

Five Things carries the practice label. It is on the list because it helps a lot of people and costs nothing, not because a study said so, and we would rather tell you that than dress it up.

Is any of this a replacement for treatment?

No. These are things to do in a moment, not care. They belong alongside a doctor, a therapist, a meeting, a sponsor, a friend who picks up the phone. If you are physically dependent on alcohol or on benzodiazepines, stopping suddenly can be dangerous, and that is a conversation to have with a clinician rather than with an app.

Marrow is a peer-support companion. It is not therapy, medical care, or a crisis service.

what this page is not

The honest limits.

  • None of this is medical advice. No dosing, no diagnosis, no opinion on your medication. If something here feels physically wrong while you are doing it, stop doing it and speak to a clinician.
  • A surge is a moment, not a plan. Twelve good minutes do not add up to recovery on their own. What holds is people, and repetition, and time. These are for getting you to the other side of an hour so the rest has a chance.
  • The evidence sits behind the technique, not behind Marrow. The studies we cite tested breathing, or urge surfing, or if-then plans. None of them tested this app. We have not been measured, and we will say so until we have.
  • Nothing you do on this page is saved. The ratings you tap here live in the browser tab and go when you close it. Nothing is sent anywhere, and there is no account.
