To be honest, eating pizza since Monday hasn't been the biggest struggle of this challenge, it's actually been somewhat of a delight.
Being able to only drink water for a week has been wearing me thin. I drink tons of water normally, but the random Gatorade or glass of milk helps break through the monotony of just drinking water. Right now, my morale is shot. I am drowning in a watery pool of leftover pizza and would do awful things for a blue Gatorade right now (Not that Glacier Freeze crap either, Cool Blue, the original).
