Ick, I know I'd much rather have a water, or poweraid during or after exercise... I wonder how many drivers actually like that stuff...
And I know that before I play a hockey game, do not drink coffee, the caffeine gives me the jitters, and it VERY MUCH throws me off my game. Wonder if any drivers experience something similar when they drink a full throttle during a race (or I bet they just take a sip when the cameras are on)
