Not my worst time but a memorable one was when I collapsed, face first, onto a wood floor and the first (and only) DG Con at Kender's house in San Francisco.
This was after many hours spent in a hot tub drinking one of the foulest things I've ever had the misfortune to drink (Jaegermeister mixed with peppermint schnapps) along with some weird little bottles of stuff Creepster brought (I don't even remember what they were)
I think I was one of the only people to avoid vomiting that night but I did have a wonderful bump on my head the next day.
one pack was plum shnapps, the other must have been apple rye or something
i dont think it was peach
