Part of the complete guide to understanding addiction

Alcohol is a commonly used substance in the USA - nearly 90 percent of adults consume alcohol in their lifetime. While alcohol can be safe when used in moderation, it has negative ramifications in many areas of life when abused. When consumed in excess this can lead to addiction, and alcohol withdrawal does not follow as automatically. According to the NIAAA [1], alcohol accounts for 3.3 million deaths a year globally, and approximately 16 million people in the USA (around the entire population of New York) are affected by alcohol use disorder (AUD).

Alcoholism is chronic, and occurs when a person’s uncontrolled drinking turns problematic. It is challenging to overcome, and it may seem insurmountable to someone who has not yet started on the path to recovery. However, sobriety is always possible with proper treatment and a long-term care plan.

Alcohol withdrawal occurs when a person who consistently and heavily consumes alcohol, stops drinking. The body reacts to the sudden lack of alcohol and triggers a physical response. Alcohol is a depressant that affects the brain and causes it to produce more GABA (a neurotransmitter with a calming and euphoric effect) and less glutamate (a neurotransmitter responsible for making you excitable). When alcohol is continuously misused, the opposite effect occurs, and the brain will produce more glutamate to maintain balance. Once the alcohol is withdrawn, the brain will be overstimulated due to the extra production of glutamate. This causes withdrawal symptoms, which will last until the brain readapts to the absence of alcohol and resumes normal production levels.

Alcohol Withdrawal Symptoms

Detox from alcohol can lead to physical symptoms ranging from mildly uncomfortable to severe and dangerous.

For many people, the alcohol detox symptoms can start on the more mild side, but then increase over time and eventually peak and subside.

The most typical signs of alcohol withdrawal include:

  • Shaking
  • Mild sweating
  • Mild anxiety
  • Fatigue
  • Headaches
  • Insomnia
  • Nausea
  • Vomiting
  • Irritability
  • High blood pressure
  • Elevated body temperature
  • Elevated heart rate
  • Irregular heartbeat
  • Seizures
  • Tremors
  • Depression
  • Altered consciousness
  • Hallucinations
  • Delirium tremens (DTs)

Alcohol Withdrawal Timeline

So, how long does alcohol withdrawal last? Withdrawal from alcohol starts approximately six hours after the last drink, and includes both physical and mental symptoms. The length and intensity of symptoms vary according to each individual. Among other variables, it will depend upon the length and strength of abuse and each person’s physical condition. That being said, symptoms will typically develop in three stages.

Stage 1: During the first stage, symptoms tend to be mild. This includes anxiety, sleeplessness, stomach pain, and nausea. It is common for many people to recover from withdrawal symptoms after this stage.

Stage 2: Serious symptoms, which can include seizures, usually begin 48 hours after the last drink. More than five percent of people will experience this phase during withdrawal. Symptoms can include high blood pressure, irregular heartbeat, elevated body temperature, and mental confusion.

Stage 3: The third stage begins 72 hours (about 3 days) after the last drink and can include fever, seizures, agitation, and hallucinations. Delirium tremens [2] can also develop during this stage.

Some people will experience post-acute withdrawal syndrome (PAWS) as well. This syndrome is characterized by withdrawal symptoms lingering for a longer period of time than usual.

Alcohol Withdrawal Risk Factors

Some of the risk factors which affect the severity of alcohol withdrawal symptoms include:

  • Duration and frequency of alcohol use – the greater the frequency of alcohol use, and the larger the quantity ingested, the more severe withdrawal symptoms tend to be.
  • Age – the older a person is, the more likely they are to experience severe symptoms.
  • Physical or mental disorders – both physical and mental conditions can complicate and exacerbate withdrawal symptoms.
  • Previous history of severe alcohol withdrawal symptoms – if a person has prior experience of severe withdrawal symptoms it is likely that they will again suffer from intense withdrawal symptoms.
  • Earlier withdrawal attempts – withdrawal symptoms increase in severity each time a person attempts to quit alcohol use.

Can Alcohol Withdrawal be Fatal?

Alcohol is one of the only substances that carries the risk of fatality during withdrawal.

How to Manage Alcohol Withdrawal at Home

It is critical that one seeks medical care in an alcohol detox facility when stopping to drink and not try alcohol withdrawal management at home.

The symptoms described below can be dangerous and potentially fatal. If someone experiences these symptoms, they should seek medical attention immediately. Hospitalization may be necessary.

  • Tremors can begin between five to ten hours after the last drink and can last for two days. Tremors may be accompanied by a rapid pulse, rapid breathing, increased blood pressure, as well as psychological symptoms such as anxiety, hyper-alertness, irritability, nightmares or vivid dreams, and insomnia.
  • Alcohol hallucinosis can begin between 12 to 24 hours after the last drink and last for two days. Hallucinosis is experienced as mental hallucinations, such as seeing objects moving, or other detailed visions.
  • Alcohol withdrawal seizures can begin between 6 to 48 hours after the last drink, and several seizures will usually occur within a few hours. The riskiest time for seizures is after the first 24 hours of withdrawal but seizures can occur any time between the first 6 hours up to 72 hours.
  • Delirium tremens, or DTS, can begin two or three days after the last drink. It is characterized by tremors, and changes in breathing, temperature, and circulation. These shifts can divert blood flow from the brain, resulting in temporary loss of consciousness, stupor, nervous or angry behavior, irrational beliefs, soaking sweats, sleep disturbances, and hallucinations.

Withdrawal Shakes

During withdrawal, patients will often experience withdrawal shakes, which can be caused by anxiety and/or stress. However, if such tremors are unabating, they may denote a more severe condition developed through years of alcohol abuse. Tremors can be a sign of damage to the cerebellum, the area of the brain that regulates balance and movement coordination. Another cause can be liver disease, which in its later stages will cause tremor-like symptoms.

How to Stop Withdrawal Shakes?

If one is experiencing shakes or tremors, they should consult with a doctor to determine if there is any serious underlying cause. A doctor may prescribe anti-anxiety alcohol withdrawal medication, or suggest a nutritious diet and increased hydration. Whether due to withdrawal or a more serious underlying condition, tremors should not be ignored.

Sleeping During Alcohol Detox

Alcohol withdrawal can be mistaken for a commonplace hangover, and often people are left alone to “sleep it off”. Sleepiness is a common symptom during alcohol detox. Since it may signify more serious problems, it is critical that symptoms of fatigue during detox are supervised and treated medically.

How to Manage Alcohol Withdrawal

The withdrawal process can be challenging, but is very possible to get through safely. It is important to have support in place to safely endure the withdrawal process, and prevent failed withdrawal attempts.

Here are some ways to prepare for alcohol withdrawal:

  • Inform friends and family so they can check up on you. It is important not to be alone in case of severe symptoms.
  • Remove alcohol triggers such as friends who drink, or alcohol itself – to alleviate cravings.
  • Prepare fluids – dehydration may occur due to excessive vomiting. Stock up on fluids.
  • Call for medical help – be prepared to call for medical help in case of emergency.
  • Check into a rehab – Alcohol detox can be a matter of life and death. It is far safer to detox in a licensed facility under supervision and professional care. Avenues Recovery can offer you expert rehabilitation options to safely withdraw from alcohol addiction.

It is helpful to keep in mind that proper nutrition in recovery can contribute to alleviating withdrawal symptoms.

Alcohol Addiction Treatment

It is always best to have a professional assess alcohol withdrawal symptoms and put together an individualized treatment plan. Withdrawal treatment may include behavioral programs, support, and medication if necessary.

Some treatment options are:

  • Outpatient care: This will include regular office visits for counseling, medication, and support.
  • Partial hospitalization or intensive outpatient: Patients will receive outpatient care for complex needs.
  • Inpatient rehab: It is often beneficial to seek treatment in an inpatient rehab facility, where one can receive 24-hour medical support and supervision.

Medication for Alcohol Withdrawal

In some cases, medical treatment is needed to assist with withdrawal symptoms. For severe symptoms, hospital treatment may be needed. Otherwise, a doctor may prescribe anxiety-relief medication (such as benzodiazepines) to alleviate psychological symptoms. The FDA has also approved three non-addictive medications for alcohol use disorder: naltrexone, acamprosate, and disulfiram.
