Symptoms of withdrawal can be psychological and physical. How much, how often and for how long someone consumed alcohol impacts their withdrawal symptoms. People who drink often and a lot experience the most extreme withdrawal symptoms.
Delirium tremens is a severe form of alcohol withdrawal. It causes confusion, tremors and hallucinations.
Delirium tremens is most common in people who drink the equivalent of one pint of liquor every day for several months.
Delirium tremens is life-threatening. It can cause heart problems and fatal injuries from sudden seizures. Seizures may occur 12 to 48 hours after stopping drinking. Approximately 1 out of every 20 people who experience withdrawal will suffer from delirium tremens.
Duration of Withdrawal
The first symptoms of withdrawal usually appear within the first 5 to 10 hours after the last drink. Tremors or shakes are common first signs of withdrawal. In severe cases, seizures and hallucinations follow.
Alcohol withdrawal is the worst a day or two after the last drink. Symptoms start subsiding throughout the following week.
Physical symptoms taper off sooner than psychological ones do. Long-term effects can last for months or even years after the last drink. These may include sleep disturbances or lingering depression.
