Did you drink all your water today? I filled my pitcher, then was bisy and didn't have access to it. I had a 1/2 liter bottle of water and filled my regular water bottle (20 oz) a couple of times, but it was while I was out. I also had a glass of juice along with some coffee. All in all, I think I've done pretty good, and am drinking some more this evening. I wish I had measured it out, but I do know I managed to drink quite a bit.
