Yeah, it sounds like a mix of pills and booze to do that. An old friend of mine who I use to party with, a girl, I'm a guy, someone gave her roofies in her drink without her knowing...the date rape drug, and she started feeling sick and delirious, so we took her to the hospital where she nearly died on the way there.

Too bad about your friend. I've lost a few friends to silly things like a good time. You'll get over it, but it will take time.

Good luck.
