I've had a few issues with invites to parties, wedding receptions etc, but for the most part I won't even tell anyone I'm teetotal. I'm okay with people drinking in my company; the problem arises if I go into a pub or club on my own, but that is very rare nowadays. I'm quite happy to be at home with my books, manuscripts, and medieval manorial rolls. I'm a bit of a boring sod these days.
