Actually I used to drink a lot but it does not have any common with picking up, I just like alcohol and even when sitting at home or after sport, during dinner, during meeting with a friend I'd love to have a drink or open some bottles of beer. I think small amounts of alco does not do any harm to your seduction abilities and there's no need to definitely reject alco.
But I don't like drunken girls and I wouldn't feel fair to a woman who was just used by me because she lost control

I'd treat this as a kind of deception.
