That's good, man. I find it works better if I don't trumpet it, e.g. I don't put myself in a situation where I'm at a bar or whatever and I'm drinking Coke Zero all night. That encourages people to be obnoxious: have a beer you faggot, etc.
But of course you don't want to isolate yourself either. It's a delicate balance. I find myself sending cheerful texts to my friends who drink (ahem, all of them) and just kind of making excuses when they ask me to go out. They're starting to get the idea.
When my daughter has a hold of something she can't have (plastic bag, iPod, whatever) and she seems to be really enjoying it, I have to give her something else before I take away the offending item, otherwise she will go apeshit and bang her big Irish head against the floor. We need diversions like that too. For me it's been movies (SERIOUSLY HOW HAVE I NEVER SEEN A DAVID LYNCH FILM), music, and (sorry Streethop) some good old-fashioned Bible study. I've also been going to meetings just to be around other people who are trying not to drink. This has been amazing. It's especially poignant to see a young guy, little older than I am, who let alcohol completely wreck his life. It actually makes me happy because I say to myself, "Well, I'm not as bad as that guy, but if I don't stop, I probably will be." Big motivator. It has the unintended effect of making me doubt my addiction cred, though: I share with the group and my shit is always tepid, minor league stuff. No, I didn't lose my job, crash my car, or end up alone. But I'm the only one in there thinking like that. They all seem happy I decided to stop when I did and they take my problem and its significance for what it is. They know, like I do, that the best case for an alcholic is a life of quiet desperation.
One last thing. People get infuriated when you suggest this, but if you recoil at/rail against/are fascinated by/debunk 12-step programs, there is a possibility it's because you have a messed up relationship with drugs or alcohol. Maybe you owe it to yourself to check it out? Go, sit in the back, be disgusted, then go home and call it crap. It's nobody's business but your own. And if you want to stay sober, but dislike meetings, I wish you well--sincerely, humbly, with all my heart.
But the people I'm meeting now are trying to help me because it's good for them to help another addict. I'm putting myself out there too, for the first time in years, and that's a vital means of keeping myself from getting wasted, too.
