Will a Diet Coke give you the same effect as a Coke? I'm curious how much of your bouncing is due to the caffeine versus the sugar and/or some synergism.
I think so? I've had the same question and have been meaning to do a actual controlled experiment, but haven't ever gotten around to it. I know I react badly to sugar, and I'm fairly certain I also react badly to caffeine separately, but don't have enough data points to draw a solid conclusion yet.
