I got let down by a dealer once (ok, it was more than once, but for the sake of the story...)...anyways, there was three of us, and we all needed a buzz real bad - this was in the days when I was a hedonistic maniac, you understand.
So, we each bought a packet of Pro-Plus each, and ate the entire contents in one go, washed down with Red Bull - two cans.

DO NOT EVER DO THIS!!!

I was a jittery wreck, agressive as hell, and felt like shit warmed up.
*Blows chunks*

Sheesh, one for the scrap-book, to be sure
