I've never had the beer goggles thing happen to me in the way of looks - if a guy is dorky or nasty, ain't no amount of alcohol gonna change that for me! However, I have had situations where the guy seemed a HELL of a lot more interesting while we were drinking, but when I went out with him when sober, I found him totally boring, but still cute. Go figure.
I don't know too many of my girl friends who have had the same kind of drastic beer goggle experiences that our guy friends have. I'm not saying that guys don't have self-control - instead I think there really are women who cake on the makeup and look good in low lights and the morning after look like they need an exorcist. I think it's harder for men to change the way they look - unless they wear makeup that is.
