i don't do much sugar. and i mostly drink decaf coffee, iced tea and water. so soda does the same thing to me. one time at a passover dinner, i got sugar drunk from the Manishevitz grape juice.
I try to watch my caffeine more than sugar. I don't like many diet drinks, and I drink more soda than I should. I do love ice tea tho it tastes like crap made with decaf tea bags (to me anyway). I am on a lemonade kick right now.
