Cat4554, an alcoholic can be a child, sibling, parent or spouse of another alcoholic. That's why they are called "double winners." They can go to AA for their own physical and emotional sobriety, and to Al-Anon because they've been or are being affected by another person's alcoholism. They say, "AA helps keep me sober and Al-Anon helps keep me sane." Al-Anon helps with the "insanity" of codependency, controlling, enabling and focusing on changing other people, places, things. Al-Anon helps bring the focus back on oneself and on what one can change about oneself and one's circumstances today (not yesterday or tomorrow), and teaches one to accept what one cannot change.
