First of all, so glad you posted! How about saying you're diabetic? That wouldn't be any kind of disease that would be off-putting to a man, yet would clearly explain why you can't drink right now...your sugar levels are all out of whack. Also explains why you could drink before, as before they were fine (or you didn't know about the "diabetes" yet). Yes, I'm a fabulous liar.
Making such a big change in your job is a huge step. There are a lot of us here who've had "alternative" careers. You might find the women are more open to discussing it if you also posted in the women's forum.
