I used to drink a lot of beer. I went to the pub regularly, beer festivals every year, always had bottled beer in the house and did home brew. Oddly, since going teetotal a few years ago I can't stand the smell or taste of beer any more. Even walking past a pub sometimes I find the smell revolting. I'm not sure if I've "unacquired" the taste or maybe I just associate that smell/taste with being out, drunk and feeling terrible.
