Juice was my weakness! I was never able to drink anything carbonated but if there was juice around I would always pick it over water. The problem was that when I drink its usually a liter at a time. I drink a liter of water at a time and I used to drink a liter of orange juice at a time and not realize it. I have gone through a gallon of orange juice in a day before. Those calories add up... especially when it isnt all that filling.
