Stopping drinking alcohol abruptly after a long period of heavy drinking can lead to a range of withdrawal symptoms, some of which can be serious and even life-threatening. In severe cases, sudden alcohol withdrawal can cause delirium tremens (DTs), a condition that can lead to seizures, hallucinations, and even death. It is important to seek medical attention if you or someone you know is experiencing alcohol withdrawal symptoms. Medical professionals can provide treatment and support to help manage the symptoms and prevent complications.
