For an alcoholic, self-rehabilitation is never easy. The physical and mental craving is intense. In addition, alcoholics must face themselves psychologically and there is no alcohol available to dull the pain of self-recognition. As the body and mind slowly repair themselves, not drinking may become easier. Many reformed alcoholics start drinking again.
Society is no help here.
Sit in a bar and drink far too much far too often and most often nobody will care as long as you pay up and make no trouble. Bt if you take too many drugs far too often, you are more likely to draw attention. Such is the tolerance for alcohol in society. Some 65 years ago, Alcoholics Anonymous was set up to help alcoholics help themselves. Its founding spirit is essentially non-judgmental.
