How much water do you drink per day?

500 ml.

it depends really. I dont drink that much pure water, but i drink alot of those frozen concentrate juices that are like 3/4 water and then about 1/2 gallon of milk a day.

At least 3/4's of a gallon, most days around a gallon or a bit more. Don't know why, but I've always consumed a lot of water. Definitely helps me feel more clear-headed than when I'm not drinking as much.
