Why Can't I Get Wired Like Normal People?

Yesterday at work a co-worker gave me an energy drink called "Full Throttle." That was a mistake. I felt sort-of good for a while, then nauseated, then shaky, then irritable, then all out mentally ill.

I couldn't come down off this stuff for the life of me. I spent most of last night tossing and turning in bed, feeling strange and ill.
