My brother tried AA and thought it was a worthless. I have read that their success rate is not good (LostPhil scolded me when I said this before). I believe you can stop the drinking on your own now that you know how much it means to your daughters.

Check out your local small college to see if they have any activities.
Have patience, you may not find a friend right away, but if you get out you are bound to find someone.
