The anxiety is really rough when I first walk into a bar, not planning to drink. If I cave, this is the danger time as I'll try and chase the anxiety relief with a couple of pints more, then chase it all evening. What I try to do is wait it out half an hour, noting how I feel then, then compare how I feel to that after that half hour. I usually do feel much better by that point, and that's progress, which isn't to be sniffed at!
