My thoughts before I relapsed? I was under a great deal of stress, and didn't see a better way to cope with it, and said, "F it" to myself. I didn't really have regrets until the next day, although I have never relapsed and gotten drunk- so the regrets I had were that I had relapsed, not what I had done while drinking.
Each time, I "got back on the horse" right away, and I guess maybe I'm just stubborn- but I had to learn the hard way how it felt to let myself and others down. I have now added that to my toolbox and whenever I feel like a drink is a good idea, it's one of the things I remind myself that help to stop that line of thinking.
best to you, s
