Glad you're back and trying. Every alcoholic knows that drinking again when they've managed to put some sober days together is an error...afterwards. That becomes very clear and there's no doubt at all. You couldn't possibly understand it better than you do right now.
Which does you no good whenever you've been sober some days and it suddenly seems like a wonderful idea. That's what your recent experience can teach you if you'll allow yourself to look at it squarely. If you can, then you stand a chance to accept that you'll be needing an answer than will work for you better than the last one to allow this newest cessation to be more than another lap around the track.
