To each his or her own, but I totally don't buy the "simply a physical problem" idea. The science behind TSM is very convincing, so I accept that there is a physical aspect that NAL can help me address, but as I've "soapboxed" all over these boards, I believe the part about finding other ways to deal with feelings and emotional problems is AT LEAST as important. Chrissie's comment about "learned to handle emotions and situations w/out having alcohol to rely on" is a very big deal for me. I was absolutely using AL as the quick and easy way to chase away anger, resentment, jealousy, disappointment, depression, self-loathing, you name it. Feel bad about ANYTHING? Booze will make it go away for a few hours, and the hell with tomorrow. Real smart, huh? For you, now, that may not be a good fit; if you've abstained for years, apparently you've worked out other ways of dealing with life's problems. I don't know anything much about what you were like in your drinking days, so I'm opining in the blind here.
I completely understand your resenting not being able to have one occasionally in appropriate situations. I did eight years of AA, though 7 1/2 of them I was totally faking it and taking nothing away from the meetings. My #1 problem was something I heard at the very beginning of every single meeting: "The only requirement for AA membership is a desire to stop drinking." Thing is, I did NOT have a desire to stop drinking, ever; I had a desire to stop drinking
pathologically. So I felt like a total hypocrite the entire time, even though in the final few months I did at last open my mind to the good stuff in spite of that. But to the point, what I wanted was pretty much what you say you want -- to be able to have a social drink on occasion without going off the deep end. Partly it was about NOT accepting the "powerless over alcohol" thing, which was my second biggest issue with AA. (Well, maybe third, the Higher Power thing is right up there at the top of my list too.) I was raised to believe I must be in control of my fate as much as possible, and accepting that I could never drink because I was incapable of exercising control of my own behavior was a very hard pill to swallow. That being said, though, part of my "head work" has been to get it through my thick skull that there are a whole lot more things outside my control than I might like to believe!
As to will it work after nine years abstinent, as I understand the science, yes. Your receptors were made hypersensitive to alcohol back in your drinking days, and are still set on high even though you no longer drink. Kind of like cranking the TV volume up to 100, then muting it -- hit the un-mute button and you'd better be holding on tight. So the first one without NAL will evoke a big pleasure reaction even after all this time, whereas with NAL it won't. That's the physiological reality behind AA's insistence on "just don't take the first drink." You have the book, so you can look that part up and see if I remember it right; I was a cheapskate and borrowed it from the library.
I just re-read my wordy second paragraph and noticed something: ...
to be able to have a social drink on occasion without going off the deep end. The operative word is ABLE. For me, I sometimes think it's not so much about actually having a drink or two, as knowing I CAN if I want to, without losing control. My six months of TSM are actually a little odd in that respect, as I've been making sure I have some AL several days a week in order to let the NAL do its thing. At this point, I'm thinking maybe I need to back off on that and just let it happen more naturally and casually, instead of treating it as some kind of a scheduled "cure" regimen. That's a dilemma you and I face that isn't shared by most posters here, who are trying to come down from very large numbers -- deciding which days are going to be drinking days just isn't an issue!

Sorry, folks in that situation, no disrespect intended.
