It sounds like you're doing great. I am not in a 12 step program so I can't speak to that but I also had a bad patch about 4 months in. It lasted about a week. I figured out it was a kind of simple thing. I was doing enough enjoyable things during the day. So I got back on track with that.
After years of 'solving' all my problems with alcohol it's hard to remember sometimes that action is the way out!
