Symptoms you may experience with alcohol withdrawal include:

  • sweating
  • sleeping difficulties
  • hallucinations
  • mood changes, such as depression or anxiety
  • agitation
  • hand tremors
  • seizures


If you experience multiple episodes of alcohol withdrawal, you may find that the symptoms begin to worsen each time. This is known as kindling.

Kindling can cause more severe symptoms, such as seizures. These result from the activation of brain and nerve cells that happens when you remove alcohol from your body following heavy use. This activation causes hyperexcitability, or excessive excitability, which can lead to seizures.

Kindling can also involve tremors and agitation.

Withdrawal delirium

Alcohol withdrawal delirium, or delirium tremens, is a rare but potentially serious complication of alcohol withdrawal that can be fatal. Almost 2% of people with alcohol dependence will experience alcohol withdrawal delirium.

The symptoms of alcohol withdrawal delirium can include agitation and hallucinations.

Having a doctor monitor your symptoms can help you reduce your alcohol intake as safely as possible and lower the risk of more serious complications.

However, it is important to note that the exact timeline for withdrawal symptoms can differ for each person.

What is alcohol withdrawal syndrome?

Alcohol withdrawal syndrome (AWS) is a term that medical professionals use to describe the set of symptoms a person with an alcohol use disorder typically experiences when they stop using alcohol.

About 8% of people who require a hospital stay for alcohol use disorder experience AWS. In severe cases, an individual may require treatment in an intensive care unit.

The Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM‐5) outlines the criteria for an AWS diagnosis as follows:

  1. There is clear evidence that an individual has stopped or reduced their alcohol intake following frequent or heavy use.
  2. There is no other medical condition or mental or behavioral disorder that may be responsible for the symptoms.

What is acute alcohol withdrawal syndrome?

Acute AWS is a term that describes the initial symptoms of alcohol withdrawal. These may occur anywhere from a few hours to about 5 days following cessation.

These symptoms can be intense and may progress in severity.

Following acute AWS, some people may experience post-acute withdrawal syndrome (PAWS).

What is post-acute withdrawal syndrome?

PAWS refers to prolonged side effects that some people experience following alcohol withdrawal.

PAWS can last anywhere from a few weeks to a year.

Symptoms that may occur with PAWS include:

  • low energy
  • sleeping difficulties
  • irritability
  • emotional outbursts
  • anxiety
  • memory problems
  • chronic nausea
  • dizziness
  • delayed reflexes
  • intense cravings

Intense cravings can cause an individual to relapse. It is important to consult a doctor if you are experiencing PAWS so that they can help you manage your symptoms.

What causes alcohol withdrawal?

Alcohol affects the central nervous system and the brain. Excessive alcohol consumption can cause the brain and body to become dependent on alcohol.

When a person stops drinking alcohol after frequent or heavy use, the brain and body have to readjust to the chemical imbalances.

These imbalances can cause you to experience symptoms of alcohol withdrawal. Neurotransmitters no longer receive the sedative properties associated with alcohol, which can result in feelings of anxiety or irritability.

Additionally, the activation of brain and nerve cells can result in hyperexcitability. This can cause more severe symptoms, such as seizures.

Contact your doctor for more information about what happens to your body during alcohol withdrawal.

How do I relieve symptoms of alcohol withdrawal?

Doctors may recommend an alcohol treatment program to help you manage your symptoms of alcohol withdrawal. This program can include:

  • Inpatient rehabilitation: This offers a safe and supervised environment in which experienced medical professionals can assist you with managing your symptoms.
  • Outpatient rehabilitation: This option may be preferable in cases of less severe alcohol misuse.
  • Alcohol rehabilitation counseling: A counselor can help you manage your symptoms and identify any underlying causes of alcohol use disorder.
  • Support groups: You may find it helpful to meet and receive support from other people going through a similar experience.

Are there any alcohol withdrawal medications available?

Your doctor may prescribe medication to help you manage your symptoms of alcohol withdrawal. They might recommend chlordiazepoxide (Librium), which can also help alleviate symptoms of anxiety.

Some medications can also help reduce the urge to drink alcohol. These include acamprosate (Campral) and naltrexone (Vivitrol).

In cases of delirium tremens, your doctor may prescribe benzodiazepines.

Contact your doctor for more information about ways in which you can manage the symptoms of alcohol withdrawal.

When should I see a doctor?

Contact a doctor if you have concerns about alcohol dependency. The doctor will be able to provide you with information about safe ways to reduce your alcohol intake, and they will also be able to signpost you to specialized sources of support for people with alcohol use disorders.

You should also contact a doctor if you are experiencing alcohol withdrawal symptoms. They will be able to advise you on how to manage your symptoms and reduce the risk of delirium tremens.

How much alcohol is too much?

Excessive drinking includes binge drinking and heavy drinking.

According to the Centers for Disease Control and Prevention (CDC), binge drinking refers to drinking four or more drinks over 2–3 hours for females and five or more drinks for males.

Heavy drinking is eight drinks or more per week for females and 15 drinks or more for males.

In the United States, an individual drink is:

  • 5 ounces (oz) of 12% ABV wine
  • 8 oz of 7% ABV malt liquor
  • 12 oz of 5% ABV beer
  • 1.5 ounces of 40% ABV (80-proof) distilled spirits or liquor, which includes:
    • whiskey
    • vodka
    • rum
    • gin
