Causes

By Mayo Clinic staff

Alcohol addiction — physical dependence on alcohol — occurs gradually. Over time, drinking too much changes the balance of chemicals in your brain associated with the pleasurable aspects of drinking alcohol. Excessive, long-term drinking can affect the balance of these chemicals, causing your body to crave alcohol to restore good feelings or to avoid negative feelings.
