Welcome back Cohiba.
Sounds like you've changed your tune a bit.. I believe before you just wanted some time sober, and it almost sounded like you were "planning your relapse, if you will. This time it sounds like you mean business, which is a good change. Once you realize what a problem you have it gets a little easier to fight it.
This is definitely a good place to start and there's so much support on here. Just stick with it and remember what it feels like when you're not hung over and embarrassed
nymets, I love what you said about playing the tape forward. I haven't heard that expression but what sense it makes! I'm always thinking about what I'm feeling in the moment, or what I felt in the past, never what I'm going to feel tomorrow...
