Hoping for a speedy recovery, Mr. Wensel! Seriously, those energy drinks can really mess someone up. I remember when I was studying for finals week and I downed 3 cans of Full Throttle. Felt all right and not jittery. And then later the same night I took some pre-workout (another injection of caffeine) and started getting pronounced heart palpitations while lifting. Guess it was that last drink that tipped me right over the edge.
