Seems to me you're already that drunk that its too late to reply, but what the hell.

Its not the sugar that make you hung over, its the diuretic effect of the alcohol so you end up dehydrated
Try and down a glass or two water somewhere near the end of this bender and you'll feel much better in the morning

Not drunk at all. I was just thinking about this because I saw the Zima in my fridge and it tasted so artificial and shitty that if it had artificial sweeteners would it be better for a hangover

I drink rum and diet coke all the time.
