I have to say I think sober4metoday is right. I agree no sense in beating yourself up about it... but you seem pretty lighthearted about the whole thing. I mean, if I spent the weekend at the Taj Mahal, but drank, I'd consider the weekend anything but amazing.
I'm glad you're talking about ratcheting things up, getting serious about AA. You've been a member here for a year and a half. Would hate to see another year or more slip by.
