I think I'll add that I wouldn't count on your sudden "ambivalence" towards alcohol to keep you sober. I've thought that before after a bout of drinking, only still to return to it later. I'm no expert on staying sober, but I think a key is accepting you won't drink whether you want to or not.
I'm an alcoholic. I think to expect that there won't be any times when I want to drink a bit unrealistic. That's the battle.
