Sleep after quitting alcohol: what to expect
Alcohol can help you fall asleep, but it makes the rest of the night worse. It cuts down dreaming (REM) sleep, wakes you more often in the second half of the night and makes you need the loo. So it’s common for sleep to feel strange for a little while after you stop, before it gets much better than it was.
The first few nights
You might find it harder to drop off, wake in the night or feel restless. This is your brain adjusting to sleeping without a sedative. For people who drank moderately, it usually settles within days.
Vivid dreams
With alcohol gone, your brain catches up on the dreaming sleep it missed. Dreams can be more frequent, more vivid and sometimes about drinking. It doesn’t mean you’re about to drink. It’s a sign your sleep is rebalancing.
Night sweats
Some sweating at night for the first few days is common. If it comes with shaking, a racing heart, anxiety that’s getting worse, confusion or seeing things, that can be withdrawal: call NHS 111 or your GP, or 999 in an emergency. How to stop drinking safely.
When it gets better
Within about a week, most people’s resting heart rate is back to normal and sleep starts to feel more restful. By two to four weeks, many say they’re sleeping better than they have in years and waking up clearer. If you drank heavily for a long time, sleep can take longer to fully settle, sometimes months, but it does keep improving.
Tips for sleeping better
- Go to bed and get up at the same time, even at weekends.
- Cut caffeine after midday.
- Build a wind-down routine for the time you’d usually have a drink: a bath, a book, a walk.
- Get daylight in the morning and move during the day.
- If you can’t sleep, get up for a while and do something calm rather than lying there.
If poor sleep goes on for more than a few weeks, talk to your GP. Sources: Brower, Alcohol Research & Health 2001 (alcohol and sleep); NHS: “Insomnia”; Drinkaware: “Alcohol and sleep”.
Questions people ask
How long does insomnia last after quitting alcohol?
For most people, sleep improves within one to two weeks. People who drank heavily for a long time can find it takes several weeks or more to fully settle.
Why am I having vivid dreams after stopping drinking?
Alcohol suppresses dreaming (REM) sleep. When you stop, your brain catches up, so dreams are often more frequent and vivid for a week or two, including dreams about drinking. They’re normal and they pass.
Are night sweats normal after stopping drinking?
Sweating at night for a few days can be part of your body adjusting. If it comes with shaking, a racing heart, confusion or seeing things, get medical help straight away, as these can be signs of withdrawal.
