I only drink sports drinks when the amount of sugar in them is meaningless. I've never sat at home on the sofa and cracked open a Gatorade. In the middle of a 3 or 4 hour ride, I couldn't care less about how many calories (or sugar) are in a 20oz bottle of Gatorade.

Never deliberately chosen a Zero-anything in my life. Me and fake sugar, we don't get along.
