What happens when you
stop drinking?
The first hours are when withdrawal appears if it is going to. Shaking, sweating or bad anxiety now is a reason to call a doctor, not to push through.
Do not stop suddenly on your own if you drink heavily. Withdrawal can be dangerous without help. Talk to a doctor before making changes if you have any health concerns.
If cutting down feels unsafe or unmanageable, free and confidential help exists. NHS alcohol support.
The timeline
-
12 hours
Blood alcohol zero
Alcohol has cleared the bloodstream.
The first day is when withdrawal symptoms appear if they are going to. Shaking, sweating or anxiety in this window is the sign to speak to a doctor, not to push on.
NHS
-
1 day
Blood sugar steadies
Blood sugar begins to stabilise.
Days one to three are the medically risky stretch for anyone who was drinking heavily. Do not do this alone without advice.
NIAAA
-
2 days
Rehydrating
Dehydration reversing; headaches and fog start to lift.
Still inside the window where severe withdrawal can appear. After this it becomes uncomfortable rather than dangerous.
NHS
-
3 days
Through the worst
Withdrawal symptoms usually peak and then fade. Energy returns.
Through the first week sleep is often broken and vivid before it improves. That is the brain re-learning to sleep without a sedative.
NIAAA
-
7 days
Sleep starts rebuilding
REM sleep rebounds - often vivid and broken first. Deep, restful sleep takes weeks, not days.
Over the next week the stomach lining recovers and reflux and morning nausea ease.
NHS
-
2 weeks
Stomach settles
Stomach lining recovers, reflux eases, weight often starts to drop.
Liver fat falls fastest in this first month. It is the single biggest physical change of the whole timeline.
NHS
-
4 weeks
Liver fat falls
Liver fat can fall significantly. Skin clearer, eyes brighter.
Concentration and memory keep sharpening over the next couple of months as sleep consolidates.
NHS
-
3 months
Mind sharper
Liver markers improve; concentration and memory sharpen.
The liver keeps regenerating through the first half-year wherever there is no permanent scarring.
NIAAA
-
6 months
Liver regenerating
Substantial liver recovery where there is no permanent scarring.
Blood pressure and long-term disease risk come down steadily across the rest of the year.
NIAAA
-
1 year
Long-term risk down
Blood pressure and liver disease risk notably lower.

And the other half of it
At the app's default of £8 a day, alcohol costs about £2,922 a year. Work out your own figure — it takes a second and nothing is sent anywhere.
Why it happens
Why stopping can be dangerous
Alcohol enhances GABA, the brain's main calming signal, and suppresses glutamate, its main excitatory one. Drink heavily for long enough and the brain compensates in both directions: fewer GABA receptors, more glutamate activity. Remove the alcohol and that compensation is left uncovered - a nervous system running hot, which is the tremor, the sweating and the racing heart, and at the severe end the seizures and delirium tremens that make this the one timeline in the app with a medical warning above it.
The liver, which recovers faster than people expect
Fat accumulating in liver cells - steatosis - is the first injury and the most reversible. It begins falling within days and can drop substantially inside a month. Inflammation takes longer. Scarring, once it is fibrosis or cirrhosis, does not reverse, which is why the timeline says recovery happens where there is no permanent scarring rather than promising it everywhere.
Sleep gets worse before it gets better
Alcohol is a sedative that suppresses REM sleep. Stopping produces REM rebound: more dreaming, more vivid, and more waking. That is a sign of sleep architecture rebuilding rather than of anything going wrong, but it is genuinely unpleasant for the first week or two and it is why the timeline no longer promises restful sleep after seven days.
Where this comes from
General guidance, not medical advice. Talk to a doctor before making changes if you have any health concerns.
