Alcohol withdrawal is the changes the body goes through when a person suddenly stops drinking after prolonged and heavy alcohol use. Symptoms include trembling (shakes), insomnia, anxiety, and other physical and mental symptoms. Alcohol has a slowing effect (also called a sedating effect or depressant effect) on the brain.
Not all symptoms develop in all patients: 1  Tremors (shakes) â These usually begin within 5 to 10 hours after the last alcohol drink and typically peak at 24 to 48 hours. 2  Alcohol hallucinosis â This symptom usually begins within 12 to 24 hours after your last drink, and may last as long as 2 days once it begins.
