What alcohol withdrawal actually means?

Alcohol withdrawal happens when someone who has been drinking heavily or regularly suddenly stops or cuts back. Alcohol affects the brain and nervous system. Over time, the body adjusts to having alcohol present. When alcohol is removed, the nervous system can become overactive.

Cleveland Clinic notes that alcohol withdrawal symptoms often begin within six to 24 hours after stopping or significantly reducing heavy, long-term alcohol use, and symptoms can include anxiety, sweating, insomnia, upset stomach, increased heart rate, increased blood pressure, and heart palpitations.
