Well, buzzed & happy is still sort of drunk (you are not sober), it wasn't a teetotalers wedding. Sure, you shouldn't get so drunk that you pass out or can't remember what you did, or so drunk that you do stupid or dangerous things. (What about so drunk that you do wonderful things?

"You may not do evil so that good may come of it" [see Mike's thread on contraception], but what if I had never saved your life because I was too shy to make a spectacle of myself and jump in the river to rescue you? Alcohol makes me less self-conscious. So in that case, being drunk is the lesser evil, letting someone drown the greater one.

I hope there will be booze on my BIL's wedding next week - he's marrying a very strict protestant so I'm not exactly sure.
