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. If this happens, you hallucinate (see or feel things that are not real). It is common for people who are withdrawing from alcohol to see multiple small, similar, moving objects.
