I tend to only have enough to drink where I'd be buzzed or drunk when alone, privately with someone. I can't say I've ever had enough to drink to make myself sick, or have had a hangover (knock on wood).
I don't generally drink publicly, as I'm usually the designated driver.

I've been known to get a little silly, and a bit sexual - it's no secret that one night while I was engaged, my then fiancee and I got VERY drunk, stripped, and took pics of each other naked lying on her bed.

They're long since destroyed, of course.
