Normally it doesn't. I've been aware of theobromine, the metabolite of caffeine you're probably alluding to, for a while though. Ever since I was young, I always got "strange" effects from caffeine compared to others, and when I looked into it I found out the primary effects I get are related to theobromine. I guess I just metabolize caffeine faster, and much more so working out (don't know if the last statement is true or not, just a guess).
