I found it easy to convert from diet pop to water...and now I'm a water addict, I guess. I have a bottle in my car at all times that stays there. I have a bottle with me at work at all times and refill it every two hours. When I feel hungry, I drink a cup or so to make sure I'm not misreading thirst as hunger. Actually, I am thirsty a lot. I drink a lot, I pee a lot, I drink more, I pee more. Yup, that's pretty much my typical day.
