I would think really hard about this: I drank about 2 glasses of wine before realizing I'd made a mistake. I just can't imagine how this would happen if you were really working your program the way you needed to. I've read some stuff about the "relapse ladder" and how it starts way before we actually take the drink...we have to have a lapse in intention, commitment, somehow open a mental door, and then align that lapse with an opportunity to drink (by buying alcohol, going somewhere where it will be served without a plan, etc.) I relapsed many times, and in retrospect there was always something I should have been doing that I wasn't, or something that I wasn't doing that I should have been. This is a really good opportunity for self-reflection and adjustment.
