As a recovering alcoholic of 13 years, I can tell you your brother has absolutely no control over his choice to drink or not drink. An addiction and illness – yes, illness – like this is overpowering. I agree with Beth that you should seek an Al-Anon meeting or talk to your family doctor. Try to be as supportive as you can and try to steer your brother to AA. There are those of us in AA who will come talk to your brother, but we need to be contacted. Good luck and God bless.
