Delirium Tremens (DTs) A severe form of alcohol withdrawal called delirium tremens (DT) occurs in approximately five percent of cases. DT typically occurs around 48-96 hours after the last drink and can last from one to five days. Hallucinations can also occur earlier than the onset of DT, but do not necessarily signal the onset of DT.
The severity of withdrawal can vary from mild symptoms such as sleep disturbances and anxiety to severe and life-threatening symptoms such as delirium, hallucinations, and autonomic instability. Withdrawal usually begins 6 to 24 hours after the last drink. It can last for up to one week. This usually occurs 24 to 72 hours after alcohol cessation. 2  Delirium tremens is the most severe form of withdrawal and occurs in 5 to 20% of patients experiencing detoxification and 1/3 of patients experiencing withdrawal seizures.
