Alcohol Withdrawal Timeline
When someone stops drinking after months or years of regular alcohol use, the body doesn’t simply adjust overnight.
Alcohol impacts nearly every major system in the body, including the brain, heart, and nervous system. Once drinking stops, the body must rapidly relearn how to function without alcohol’s depressant effects.
Understanding the alcohol withdrawal timeline can help individuals and families know what to expect, when to seek help, and why medical support is so important.
If you or someone you love is considering stopping alcohol use, you don’t have to do it alone. Learn more about our Nashville addiction treatment programs on our admissions page today to get started.
What is Alcohol Withdrawal Syndrome
Alcohol Withdrawal Syndrome (AWS) occurs when someone who has been drinking heavily reduces or stops alcohol use abruptly.
Over time, the brain adapts to the presence of alcohol by changing neurotransmitter activity. When alcohol suddenly disappears, the nervous system becomes overactive, leading to withdrawal.
AWS can range from mild discomfort to severe, life-threatening complications such as seizures or delirium tremens. Not everyone will experience severe symptoms, but because withdrawal can escalate quickly, medical supervision is strongly recommended.
Common Alcohol Withdrawal Symptoms
Symptoms of Alcohol Withdrawal can vary depending on drinking patterns, overall health, genetics, and how quickly alcohol use stops.
Less common but more dangerous symptoms may also occur, including hallucinations and seizures.
Because withdrawal is unpredictable, even individuals with previously mild symptoms may experience complications during future attempts to quit drinking.
Common symptoms include:
- Headaches
- Nausea or vomiting
- Shaking or tremors
- Sweating
- Anxiety
- Irritability
- Insomnia
- Increased heart rate
- High blood pressure
- Fever
- Confusion

Common Opioid Withdrawal Symptoms
Withdrawals differ from person to person—depending on duration of use, dosage, frequency, and individual physiology. Some commonly reported symptoms include:
- Muscle aches and pains
- Anxiety, restlessness, irritability
- Sweating, chills, goosebumps
- Runny nose, tearing eyes
- Dilated pupils
- Insomnia, fatigue
- Nausea, vomiting, diarrhea
- Loss of appetite
- Abdominal cramping
- Increased heart rate, elevated blood pressure
- Yawning repeatedly
- Cravings for opioids
These symptoms often intensify during peak withdrawal and then gradually subside, though some discomfort can linger.
Alcohol Withdrawal Timeline
While the exact alcohol withdrawal timeline can differ from person to person, most people experience a recognizable pattern as the body adjusts to functioning without alcohol.
Factors like how much and how often someone drank, their overall health, age, and whether they’ve gone through withdrawal before can all influence how symptoms develop.
For some, withdrawal may feel like an intense hangover that gradually fades; for others, symptoms can escalate quickly and become dangerous without medical supervision.
6–12 Hours After the Last Drink
Symptoms may begin within hours and can include:
- Anxiety
- Irritability
- Headaches
- Nausea
- Mild tremors
- Sleep disturbances
Many people mistake these symptoms for a hangover, not realizing they are experiencing early withdrawal.
12 - 24 Hours After The Last Drink
Symptoms typically intensify. Individuals may experience:
- Sweating
- Shaking
- Increasing anxiety
- Gastrointestinal discomfort
- Difficulty concentrating
Some people begin experiencing visual, auditory, or tactile hallucinations.
24 - 72 Hours After The Last Drink
This window is considered the most dangerous period. Symptoms may peak and can include:
- Severe tremors
- High blood pressure
- Rapid heart rate
- Confusion
- Seizures
- Delirium tremens (DTs)
Delirium tremens is a medical emergency that requires immediate treatment.
4-7 Days After The Last Drink
Symptoms may gradually improve, though some individuals experience prolonged anxiety, insomnia, or mood disturbances.

What Causes Alcohol Withdrawal?
Alcohol affects neurotransmitters responsible for calming the nervous system, particularly GABA and glutamate. Over time, the brain becomes dependent on alcohol to maintain balance. When alcohol use stops suddenly:
- GABA activity drops
- Glutamate activity spikes
- The nervous system becomes overstimulated
This overstimulation causes withdrawal symptoms. The longer someone has been drinking and the larger the quantities, the more intense the withdrawal response may be.
When To Seek Help For Alcohol Addiction
Knowing when to reach out for help can be one of the hardest parts of facing alcohol addiction. Many people convince themselves they can manage it on their own, or they minimize the impact drinking has on their health and relationships.
Others feel ashamed or afraid of what treatment might involve. But asking for help is not a sign of weakness—it’s a courageous step toward stability, safety, and a healthier life.
If alcohol has become something you rely on to get through the day, to cope with stress, or to feel “normal,” it may be time to consider professional support.
Medical guidance can make withdrawal safer, more comfortable, and far more successful long-term, especially for those who have tried to stop in the past and struggled.
It is important to seek medical help if:
- Drinking has become daily or heavy
- You experience withdrawal symptoms when not drinking
- You have tried to stop before and struggled
- You have a history of seizures or delirium tremens
- You use alcohol to cope with stress or emotions
- Your drinking impacts your work, relationships, or health
If someone experiences confusion, hallucinations, seizures, extreme agitation, or uncontrollable shaking, emergency medical care is necessary. Alcohol withdrawal can become life-threatening within hours.
Alcohol Withdrawal Stages
While symptoms vary, withdrawal is generally categorized into three stages:
Stage 1: Mild Withdrawal
Begins within 6–12 hours.
- Headache
- Anxiety
- Nausea
- Restlessness
- Tremors
Stage 2: Moderate Withdrawal
Begins within 24 hours.
- Elevated blood pressure
- Rapid heart rate
- Confusion
- Increased sweating
Stage 3: Severe Withdrawal
This stage can last several days and requires immediate medical care.
- Hallucinations
- Seizures
- Delirium tremens
How Long Does It Take to Detox From Alcohol?
Most acute withdrawal symptoms resolve within 3–7 days, but the full detox and stabilization process can take longer.
Some individuals experience PAWS (Post-Acute Withdrawal Syndrome). These symptoms can last weeks or months, especially without professional support. Detoxing in a medical setting allows symptoms to be treated as they arise, improving comfort and safety.
PAWS symptoms may include:
- Anxiety
- Sleep issues
- Mood swings
- Fatigue
How Is Alcohol Withdrawal Treated?
Detox is only the first step. Long-term recovery often requires ongoing treatment such as therapy, group support, medication-assisted treatment, or structured programs.
Treatment varies depending on severity but may include:
- Medical monitoring
- IV fluids
- Nutritional support
- Medication to reduce symptoms
- Psychiatric care
- Therapy
- Stabilization planning
Medication For Alcohol Withdrawal
Medication can play a crucial role in making Alcohol Withdrawal safer and more comfortable.
During detox, the body and nervous system are adjusting rapidly, and certain medications can help reduce anxiety, prevent seizures, stabilize heart rate and blood pressure, improve sleep, and lessen the intense cravings that often accompany early recovery.
When these symptoms are managed effectively, individuals are better able to focus on healing rather than simply enduring discomfort.
Depending on a person’s history and withdrawal severity, a medical team may use medications such as benzodiazepines, anticonvulsants, beta-blockers, clonidine, naltrexone, or Vivitrol. Each serves a different purpose, whether calming the nervous system, protecting against dangerous complications, or supporting long-term sobriety by reducing urges to drink.
Because every withdrawal experience is unique, a licensed medical professional carefully determines which medications are safest and most effective for each individual. This personalized approach helps ensure comfort, stability, and the best possible start to recovery.
