I went to an evening meeting after drinking a lot during the day. I wasn't drunk (well I didn't check my BAC), but I guess that doesn't count as "dry" either. I was feeling hopeless and the only thing I could think to help me was to get to a meeting.
The leader welcomed me, asked me to share, thanked me for helping set up and clean up, and wished me well on my road to recovery.
I guess it depends on the circumstance.
