If you or a loved one struggle with drinking and want to quit, you are not alone. Drug and alcohol use has been increasing during the COVID-19 pandemic, leaving many people unsure about the best way to quit. Because alcohol withdrawal can be dangerous, make sure you have medical advice from your doctor or a rehab facility when you decide to stop drinking. 

Alcohol Withdrawal

When your body becomes used to the presence of alcohol, it starts to expect its presence. This phenomenon is called physical dependence. When you drink heavily over the long term, there is abnormal activity of neurotransmitters in your brain, including dopamine, serotonin, glutamate and gamma-aminobutyric acid (GABA). 

If you suddenly stop drinking, your brain has a chemical imbalance. This leads to a variety of side effects known as alcohol withdrawal syndrome, or AWS.

Alcohol Withdrawal Syndrome Symptoms

AWS has many symptoms. While some symptoms are common and just uncomfortable, other symptoms can be more severe and potentially deadly. 

Common Symptoms

Many common symptoms of alcohol withdrawal exist. These symptoms can range from mild to moderate to severe. They are usually rated on a scale called the CIWA (pronounced SEE-wah). This scale ranges from 0 to 7, where 0 is the absence of the symptom, and 7 is a severe form of the symptom. Symptoms include:

  • Nausea/vomiting
  • Tremors
  • Anxiety
  • Agitation
  • Sweating
  • Lack of awareness of surroundings
  • Abnormal skin sensations, like feeling like bugs are crawling over the skin
  • Visual hallucinations
  • Auditory hallucinations
  • Headache

Severe Alcohol Withdrawal Symptoms

AWS symptoms can be severe in some cases. The most serious condition that can occur is called delirium tremens, which is severe mental or nervous system changes that occur after stopping alcohol. Symptoms of delirium tremens can include:

  • Sudden confusion
  • Tremors
  • Reduced mental function
  • Agitation
  • Irritability
  • Excessive sleep, fatigue, stupor
  • Excitement or fear
  • Hallucinations 
  • Changes in energy
  • Changes in mood
  • Restlessness
  • Sensitivity to light, sound, and touch
  • Seizures
  • Death

Delirium tremens is most likely to occur in those who have previously gone through AWS, drink excessively, and/or have been drinking for more than ten years.

Alcohol Withdrawal Symptoms Timeline

Alcohol withdrawal symptoms can start soon after a person stops drinking and can last for days. Although every person experiences withdrawal differently, a common timeline is:

  • Between six and 24 hours after the last drink, AWS symptoms begin.
  • Within five days of the last drink, a person is at risk for common alcohol withdrawal symptoms, like those on the CIWA.
  • Between 48 hours and ten days after the last drink, delirium tremens symptoms can begin.

In a recent study of alcohol drinkers who had detoxed before, 95% of respondents experienced withdrawal symptoms for 2–8 days. 

Factors that Influence Withdrawal Severity

Many factors can influence the severity of alcohol withdrawal symptoms. Known risk factors for severe withdrawal include:

  • Previously experiencing AWS
  • Drinking heavily
  • Chronic heavy drinking 

In a recent surveyheavy alcohol users across the board reported withdrawal symptoms more than average. Heavy alcohol users doubled their risk for hallucinations during detox, being 2.39 times more likely than moderate or light alcohol users to experience them. Compared to others during detox, heavy drinkers were:

  • 90% more likely to experience delirium tremens 
  • 45% more likely to experience seizures 
  • 95% more likely to experience rapid heart rate
  • 147% more likely to experience hand tremors
  • 69% more likely to experience sweating
  • 65% more likely to experience nausea or vomiting

The survey also showed that polysubstance use, or using multiple substances at the same time, increases your chances of experiencing more severe withdrawal symptoms during alcohol detox. Compared to those detoxing from alcohol only, people detoxing from alcohol and at least one other substance were:

  • 2.25 times more likely to experience seizures
  • 2.14 times more likely to experience delirium tremens
  • 1.60 times more likely to experience hallucinations

Managing Withdrawal Symptoms in Alcohol Detox 

Alcohol withdrawal symptoms are difficult to manage on your own at home, which is one of the factors that makes withdrawal so dangerous. Symptoms can be more easily managed when you are under medical supervision in a rehab facility. In medical detox, you are monitored for withdrawal symptoms as the alcohol slowly leaves your body and treated accordingly.

Your medical team can treat alcohol withdrawal symptoms in multiple ways, including managing your nutrition, environment and medications. A patient with severe symptoms is sometimes treated with a long-acting benzodiazepine like diazepam (Valium), which can help block alcohol withdrawal symptoms. You may also receive vitamins like thiamine (vitamin B1) during withdrawal to prevent a condition called Wernicke’s Encephalopathy linked to heavy drinking.

Diagnosing Alcohol Withdrawal

Alcohol withdrawal is usually diagnosed based on whether a person has recently stopped drinking and is experiencing withdrawal symptoms. Doctors will often try to rule out other causes of symptoms consistent with alcohol withdrawal, like dehydration, infection, heart problems, lab abnormalities, stomach bleeding and traumatic injury.

Can You Prevent Alcohol Withdrawal Symptoms?

Alcohol withdrawal symptoms are inevitable but can be managed if the person is under around-the-clock medical care while experiencing withdrawal. Using the CIWA symptom tracker for alcohol withdrawal, doctors and nurses can closely monitor a person. When a person begins to experience symptoms, they can then be quickly treated with medication and other supports to make the experience as comfortable as possible.

Outlook for Alcohol Withdrawal

Detox is only the first step in becoming sober. If a person only goes through detox, their chances of remaining sober long-term are low.

Alcohol rehab is recommended after detox is complete to continue recovery. In rehab, you learn to explore why you began to use alcohol in the first place and learn coping strategies for living an alcohol-free life. After rehab is complete, aftercare options, including relapse prevention plans, continuing care and support groups like Alcoholics Anonymous, can help you stay sober over the long term.

Choosing How to Detox from Alcohol

To avoid alcohol withdrawal symptoms, including severe complications like delirium tremens, it is safest to detox while under medical supervision. Undergoing detox at home or suddenly quitting heavy drinking cold-turkey are not recommended because of the dangers some alcohol withdrawal symptoms pose when you are not in a medical setting.
