You know for a very long time I didn't believe in a HP. I faked it alot. I honestly saw change in the people around me. The home group I chose was a 1-3 steps meeting and they met in a rehab center. So, there was always this consistant reminder of what awaited me if I went back to drinking. Because in the end of my drinking career while I was still barely in control of my professional life... my social life went to ****.
Anyway, for what it is worth... in early soberity it is a great thing if the focus is AA or whatever road you make a decision to travel.
