Alcoholism has nothing to do with irresistible impulses or uncontrollable urges.
Alcoholism is a disease of volition.
Calling alcoholism a disease infers that there is an invasive pathology present where none exists. Calling alcoholism a disease infers the possibility of a heritable genetic lineage with a predetermined immutable eventuality where no such heritable genetic link has been proven. Calling alcoholism a disease tends to impede the motivation and the desire to change within the alcoholic for everyone knows that one is not responsible for possessing a disease. When one possesses a disease everyone readily acknowledges the lack of volitional control. Alcoholism ceases to exist when the alcoholic volitionally chooses to stop drinking.
