What is the definition or description of alcoholism?

Alcoholism: Visibly, it is continuing to drink in ways that are "out of control" despite negative consequences.It is a metabolic disorder where alcohol is not processed normally. Over time tolerance develops, (it takes more to get the desired effect). In later stages there are often withdrawal symptoms when you stop, but not always. Without a support group, many relapse after abstaining for a while.

Alcohol dependence: Alcohol and any other form of dependence can be thought of as a need to drink, not to feel good, but rather, in an effort to avoid feeling bad.
