Sudden cessation of alcohol intake is likely to produce withdrawal symptoms, including severe anxiety, tremors, hallucinations, and convulsions.
Alcohol withdrawal can be life threatening.
Long-term consumption of large quantities of alcohol can also lead to permanent damage to vital organs such as the brain and the liver.
