Great Question Stephanie!
Water seems to be a hot topic of late. Maybe b/c of the heat? Well, I agree with you, for the average person it is almost impossible to drink too much water. I wonder though if there is a point when it's not doing you any more good. Maybe not harming you but not helping you either. I guess my plan is drink the recommended 6 glasses and then drink to satisfy my thirst. I am also trying hard to avoid caffiene which will negate the water I have drank. So once I drink my water, then I allow myself to drink any non caffinated 0 point beverages (decaf tea, coffee, etc.) and if I have points (milk, juice, gatoraide etc) whenever I am thirsty.
