Drink once in a while; trying to maintain complete sobriety (abstinence, really) is setting yourself up for a fall. Sobriety and drinking are not necessarily mutually exclusive, in any practical way. Yes, you can get all pedantic and claim that even a single molecule of alcohol can influence the release/uptake of at least one neurotransmitter, thereby "affecting" you, but in practice, moderated amounts are perfectly acceptable and won't affect your functional sobriety. ...I sound like jurupa...
Should I go out with this girl that most definitely wants me as a boyfriend, when I really just want a low-key see-you-every-few-weeks acquaintance with sex on the side? I don't want to lead her on too much, but I feel I need to go out on at least one date to broach the subject.
