To some extent, I can relate to what you say - the feelings of guilt connected to anything to do with alcohol, and the dislike of the loss of control that comes with drinking too much. You say you overreacted, which in one way is true because one glass of wine drunk slowly over two hours is a very small amount of alcohol (well, if you are a sober alcoholic it's too much, but you clearly are no kind of alcoholic at all) - but since you are carrying these frightening memories from childhood, maybe it is not so much an overreaction as a reaction? If you see what I mean. I agree with Perna, this sounds like it could be a sign that you need to work on those memories and the issues they carry with them.

Another thing: I'm far from being an expert on these things, but from what I understand, the mere fact that you wanted a good wine rather than just wine is one sign that alcohol is not even potentially a problem for you. What I mean is that you mentioned having a "craving", but my understanding of alcohol cravings is that you wouldn't crave a nice wine - the fact that you did sounds like it had more to do with the taste of the wine than the fact that it's alcohol. This is something I can definitely relate to. I like good wine, that is to say, I have some notion of the kinds of wine I like and I really don't like the very cheap stuff. Which sounds like snobbery, but it isn't - it's not always true that more expensive is better - it's just a matter of finding out what you like. For me it's the same with beer, actually, and sushi, and chocolate, and tea, and other things that come in a range of qualities and varieties.
