What causes alcohol shakes?
Uncontrollable shaking, usually in the hands, is a common sign of alcohol withdrawal. The shakes also called tremors can begin 6-10 hours after the last drink, and tend to be the most pronounced 48-72 from the last alcohol consumption
Heavy alcohol consumption causes changes in brain chemistry, slowing brain activity and reducing energy levels. To overcome the sedative effect of alcohol, the brain responds by increasing nerve activity to keep the body in a heightened state of alertness. When the intake of alcohol suddenly ceases, the brain continues to deliver increased nerve activity, leading to tremors, anxiety, hyperactivity, and other withdrawal symptoms.
Once a recovering alcoholic has completely detoxed, tremors will usually resolve. Detoxification can take from a few days to a few months. However, long-term alcohol abuse can cause brain, nerve, and liver damage, which may result in permanent tremors
