I know how you are feeling. I wasn't even a daily drinker. I could easily go a few weeks without drinking, and when I was places I knew I had to be responsible and behave I could limit my drinks to 1 or 2 (although it was easier to just have none). When I would binge though- all bets were off and I would get blackout drunk and do stupid dangerous things that left me feeling guilty and suicidal for days.
I have learned it is not the amount of alcohol consumed or the frequency which it is consumed that is important. It is the way in which alcohol changes us, makes us feel bad, or otherwise negatively afffects us. If alcohol wasn't causing you to think twice you never would have entered the rooms of AA or posted here. Alcohol is obviously weighing on your mind and I'm glad you are here.
