Stopping alcohol after regular heavy drinking can cause withdrawal. Your symptoms may start within hours of your last drink. They can range from mild shaking and sweating to seizures and severe confusion.
Alcohol withdrawal can be serious. The risk is higher if you drink heavily or have had withdrawal before. Your health, drinking pattern, and use of other drugs or medicines can also affect your risk.
In 2025, 25.7 million people aged 12 or older in the U.S. had alcohol use disorder, according to the 2025 National Survey on Drug Use and Health from the Substance Abuse and Mental Health Services Administration (SAMHSA).

What Is Alcohol Withdrawal?
Alcohol affects the brain and slows the nervous system. With regular heavy drinking, your brain can adjust to this effect.
When you stop drinking, alcohol levels in your body fall. Your brain may then become too active. This can cause withdrawal symptoms.
Symptoms can start about six to eight hours after your last drink. They may get worse during the next one to three days.
You cannot always tell how severe withdrawal will become from your first symptoms. A medical assessment is the safest way to check your risk.
Common Alcohol Withdrawal Symptoms
Mild or moderate symptoms may include:
- Shaking hands
- Sweating
- Anxiety
- Headache
- Nausea or vomiting
- Trouble sleeping
- Irritability
- Fast heartbeat
- Higher blood pressure
- Restlessness
Some people also develop hallucinations. They may see or hear things that are not there.
Severe withdrawal can cause seizures or delirium tremens (DTs) and DTs can cause severe confusion, and major changes in heart rate or blood pressure.
These symptoms need urgent medical care.

This timeline is a guide. It does not predict what will happen to one person and symptoms can vary based on drinking history and health.
Who Is at Higher Risk?
Some people have a higher risk of severe withdrawal. Tell your doctor about:
- Past withdrawal seizures
- Past delirium tremens
- Earlier episodes of severe withdrawal
- Heavy or long-term alcohol use
- Other health problems
- Use of other drugs or medicines
- Poor nutrition
Past severe withdrawal is especially important. Your doctor may recommend closer monitoring or treatment in a hospital or supervised setting.
How Is Alcohol Withdrawal Treated?
Treatment depends on your symptoms and your risk. A medical team may check your:
- Heart rate
- Blood pressure
- Temperature
- Hydration
- Mental state
Doctors may use medicines to control withdrawal and reduce the risk of seizures and severe symptoms and Benzodiazepines are commonly used for alcohol withdrawal under medical supervision.

Detox also does not treat alcohol use disorder by itself. After withdrawal care, you may need counseling, or ongoing recovery support.
