Alcohol is commonly consumed as a drink in various forms. Examples are beer, wine, and hard liquor. Alcoholism is organized into three categories: mild, moderate, and severe. You could also be becoming dependent on alcohol. So, if you find it very difficult to enjoy yourself or relax without having a drink, you could have become psychologically dependent on it. Alcoholism treatment is necessary once there is a psychological or physiological dependence, especially when both kinds of dependency are present.
