Hey ARGH, I am in the April 2015 Class and made it sober 3 and a half months before I slipped. That's when I joined this class. Then I drank four more times. But I'm still in the April class and I'm still in this Class because you all help hold me accountable.
Drinking one time (even if you got really messed up) doesn't mean you failed. You came back here and posted and that makes all the difference. Maybe it can be a lesson for you: what went wrong? What can you do differently next time? Others may be able to help.
I hope that you stick with us. You can always join the September Class as well just for extra support. I hope you feel better soon!
