Omni,
If you are drinking just a few days a week you are like I was in my last drunk days.
Physically we probably are fine to quit. Mentally, as binge drinkers, we have a long road. I still crave at 21 months.
I totally relate to a fear of AA. The stigma. Meeting new people. I was scared too. I drove by early. I sat out front for a while.
You can be late if your need extra time. Then take a deep breath, be ready to feel emotional.
I always sat in the back.
The deal is, helping folks is part of our recovery. For one thing, it reminds us of how we started. It also causes release of endorphins. It is a natural high.
I might start to go again as well soon. I use SR, exercise, and prayers.
