I had that experience too. Many times after a meeting I just wanted to get drunk or wasted. It helped me to figure out what was going on there, which aspects of the meeting were getting under my skin.
The answers surprised me, they weren't as "obvious" as being around people talking about drinking, they were things that unveiled thought and mood patterns within myself.
When I moved to a place where there were no meetings, I admit, I didn't miss them. I still used the 12 steps and I have remained sober.
