I did the same damn thing yesterday except my AA meeting was the gym. I said I am going to the gym, going home for a protein shake/shower, then going to run errands. I went to the gym, protein shake, then shower. I was feeling good. I was almost sober all day, but my "errand" ended up being a "pit" stop at the bar and 2 hours later and a $35 tab which consisted of $30 in happy hour booze and a heavy buzz. And a walk home. Awesome.
Today is Friday. I have made the same plan. Let's hope it works. BTW, I have also walked out of two AA meetings and headed straight to the bar. You never feel worse then that in the morning. At least for me. Try again today! That is what I am going to do.
