As a former water-scorner and Coke addict, I'd like to add that when I drank soda or diet soda FIRST it was almost impossible to drink the 8 glasses. I fought it for a long time, but then decided to go with just water. It took a couple of weeks to adjust, but now it's a habit.

I'd still like to up water to 12 glasses, not 8. All in good time
