Answer

Delirium tremens (DTs) is the most severe form of ethanol withdrawal, manifested by altered mental status (global confusion) and sympathetic overdrive (autonomic hyperactivity), which can progress to cardiovascular collapse. Minor alcohol withdrawal is characterized by tremor, anxiety, nausea, vomiting, and insomnia. Major alcohol withdrawal signs and symptoms include visual hallucinations and auditory hallucinations, whole body tremor, vomiting, diaphoresis, and hypertension (high blood pressure).
