Zero.
I do a few ice chips if needed.
I will tell you for a few years I did raw oatmeal(the oats) for carb up the day of the show.
Nastiest thing to eat especially if all you have to moisten them is your saliva...

Just sip enough to get the granola and potato's down. With all the dyazide there won't be any water hangin around regardless.

Same here. I'll drink a small bottle (slow) between prejudging and the finals.
