Patients who have been drinking heavily for a long time are likely to experience withdrawal reactions after they stop drinking, mainly around 7-8 hours after they stop drinking. For example, abnormal craving for alcohol, body tremors, mainly tremors in the hands and feet, and some obvious physical reactions such as gastrointestinal reactions, nausea, vomiting, loss of appetite, etc., or autonomic dysfunction reactions such as sweating and fidgeting, especially feeling uncomfortable and other reactions. If these intermittent reactions are not well relieved, serious problems may occur, such as acute alcoholism patients may experience some psychiatric symptoms after withdrawal, commonly hallucinations, with hallucinations of hearing and vision being the most common. In particular, the possibility of alcoholic seizures should be prevented between 24-72 h of withdrawal. So in summary, whether it is withdrawal reactions, alcoholic psychosis, tremors, seizures or other problems are very serious and must be seen and treated promptly.
