Is it dangerous to stop drinking suddenly?
It can be, if you drink heavily every day. Withdrawal symptoms can start within 8 hours of the last drink, peak in 1 to 3 days and sometimes become life-threatening. If that’s you, stop with a doctor’s help. If you drink now and then, a dry night or a dry month is just that.
Quitting cold turkey sounds like the brave, clean way to do it, and for most people who drink it’s fine. For people who drink heavily every day, it’s a medical event. MedlinePlus says the more often you drink, the more likely you are to have withdrawal symptoms when you stop.
What we’d do
If you drink heavily every day, talk to a doctor before you stop, because withdrawal can become dangerous. Many people can be treated at home with a doctor’s help. Everyone else can stop any night.
Who’s at risk?
Stopping after years of heavy daily drinking is less like skipping dessert and more like coming off a daily medicine. Your body has got used to having it there, and taking it away all at once is the risky part.
NIAAA counts 4 or more drinks on any day for a woman, or 5 or more for a man, as heavy drinking. Someone at or over that line every day is the person this page is for. MedlinePlus adds that withdrawal can be worse in people with certain other medical problems.
What withdrawal looks like
Symptoms usually start within 8 hours of the last drink, but can start days later. They tend to peak by 24 to 72 hours, and can go on for weeks.
| Common | Also possible |
|---|---|
| Anxiety or nervousness | Sweating, clammy skin |
| Shakiness | Headache |
| Irritability and mood swings | Trouble sleeping |
| Tiredness, depression | Nausea and vomiting |
| Nightmares | Fast heart rate |
| Not thinking clearly | Tremor of the hands |
The most severe form is delirium tremens. It can bring agitation, sudden severe confusion, fever, seeing or feeling things that aren’t there, and seizures. MedlinePlus says death is possible, especially if delirium tremens occurs.
How it’s treated
MedlinePlus says people with mild to moderate withdrawal can often be treated outside a hospital, with daily visits to their provider and someone staying with them to keep an eye on them. Treatment can include medicines that ease the symptoms and blood tests. People with moderate to severe withdrawal may need a hospital or a treatment center. Most people who go through withdrawal make a full recovery.
When to get help right away
MedlinePlus says to contact your provider right away, or go to the emergency room, if you think you might be in alcohol withdrawal, especially if you drank often and recently stopped. Go to the emergency room or call 911 if seizures, fever, severe confusion, hallucinations or an irregular heartbeat appear.
If you go to the hospital for any other reason, tell the staff you’ve been drinking heavily, so they can watch for withdrawal.
