Voice in the Mirror.

Jim Burton, chronic alcoholic, is cared for by Ellen, his incredibly patient, sexy, hard-working wife. A doctor's warning that Jim could become mentally ill strikes enough fear into him that he really wants to cure himself...but can't. One night, he meets William Tobin, a fellow drunk, and finds that he helps himself by trying to help Tobin. Thus is born, amid setbacks, a group resembling Alcoholics Anonymous.
