First, congrats on your first 100 days, and hopefully many more to come. As someone who is part of an extended family that has had (and maybe still has?) drug and alcohol problems, I am sure they appreciate your efforts.

I don't drink and can tell you that socializing in general is difficult. One thing I'll throw out there which you might like are small hiking trips. Some of the state parks allow alcohol in designated areas, but many also prohibit it. I've met a few nice people in my travels who share a similar interest in the wilderness and the call of the loons. Not only is it relaxing, generally alcohol-free, but a good source of exercise as well.
