I have an easier time drinking all my water on the days that I exercise. I drink one cup while warming up (on the stationary bike) and two or three cups right after my walk.
Let's see ~ 8 glasses of water, 3 cups skim milk, 1 cup coffee, and 1 can of diet pop each day. Who has room for food?

I remember reading somewhere that when we feel hungry, we might really be thirsty. So Kimmomo3 probably has the right idea of drinking before snacking.
