Alcohol problems come from drinking too much, too fast, or too often. People with alcohol dependence are addicted to alcohol, and they can't control their drinking. When alcohol-dependent people try to stop drinking, they may feel anxious and irritable—so they may drink some more, and it becomes a vicious cycle.
Symptoms of alcohol overdose include mental confusion, difficulty remaining conscious, vomiting, seizure, trouble breathing, slow heart rate, clammy skin, dulled responses such as no gag reflex (which prevents choking), and extremely low body temperature. Alcohol overdose can lead to permanent brain damage or death.
An urge to drink can be set off by external triggers in the environment and internal ones within yourself. External triggers are people, places, things, or times of day that offer drinking opportunities or remind you of drinking.
