Just to echo Honeypig - please don't be put off by Al Anon's references to "God" or a "Higher Power." I am an atheist but have been attending Al Anon for four years, and I am immeasurably grateful for what the groups and the program have given me (including a better understanding of alcoholism and alcoholics, and an arsenal of strategies for coping with alcoholic behaviours as safely, constructively, and lovingly as possible).
Hugs to you.
