Alcohol withdrawal happens when someone who drinks heavily and regularly suddenly cuts back or stops. Symptoms range from uncomfortable — shakes, sweating, anxiety — to genuinely life-threatening. Because severe alcohol withdrawal can include seizures and a condition called delirium tremens (DTs), heavy drinkers should not detox alone. This guide explains the symptoms, the typical timeline, and the warning signs that mean you need medical help now.
If you drink heavily every day, talk to a medical professional before quitting. Withdrawal can be managed safely and comfortably with medical supervision.
Common alcohol withdrawal symptoms
Symptoms vary with how much and how long a person has been drinking. Common ones include:
- Tremors or “the shakes” (especially in the hands)
- Sweating, including night sweats
- Anxiety, irritability, and restlessness
- Nausea, vomiting, or diarrhea
- Headache and rapid heartbeat
- Trouble sleeping and vivid dreams
- Strong alcohol cravings
Alcohol withdrawal timeline
This is a general timeline based on guidance from the National Institute on Alcohol Abuse and Alcoholism (NIAAA). Individual experiences vary.
- 6–12 hours: Mild symptoms begin — anxiety, shakes, sweating, nausea, headache, trouble sleeping.
- 12–24 hours: Symptoms intensify. Some people experience hallucinations (seeing or hearing things).
- 24–48 hours: Risk of withdrawal seizures is highest in this window for some individuals.
- 48–72 hours: The window for delirium tremens (DTs) — a medical emergency involving confusion, fever, rapid heartbeat, and severe agitation.
- 5–7 days and beyond: Acute symptoms usually ease, though anxiety, sleep problems, and cravings can linger for weeks.
When alcohol withdrawal is a medical emergency
Call 911 or seek emergency care immediately if you or someone else experiences:
- A seizure
- Confusion or disorientation, severe agitation
- Hallucinations
- High fever, racing heart, or severe vomiting
These can be signs of delirium tremens, which is life-threatening without treatment. This is why medical detox exists — to keep withdrawal safe.
Why medical detox matters
In a medical detox setting, clinicians monitor your vital signs and can use medications (such as benzodiazepines) to prevent seizures, ease symptoms, and keep you comfortable. After detox, ongoing treatment — such as a partial hospitalization program or intensive outpatient program — helps address the root causes and prevent relapse. Many people also benefit from dual diagnosis care when anxiety or depression are part of the picture.

Frequently asked questions
How do I stop alcohol shakes?
Tremors are a common early withdrawal symptom. Staying hydrated and eating can help mild cases, but persistent or worsening shakes mean you should seek medical care — they can signal that withdrawal is becoming serious. Medical detox can stop the shakes safely with monitoring and medication.
Is diarrhea a symptom of alcohol withdrawal?
Yes. Gastrointestinal symptoms including diarrhea, nausea, and vomiting are common during alcohol withdrawal as the body readjusts. Severe vomiting or dehydration should be evaluated by a medical professional.
How long do alcohol cravings last?
Acute cravings are often strongest in the first week, but cravings can come and go for weeks or months. Therapy, support groups, and sometimes medication make them far more manageable over time.
How long does alcohol withdrawal last?
Acute withdrawal typically lasts about 5–7 days, with the most intense symptoms in the first 72 hours. Some symptoms like sleep disruption and anxiety can persist longer.
