Dont be so hard on yourself, water is not easy to get used to, for me beverages were always great company for my snacks ! Now that I rarely if ever snack, and when I do it isnt something that needs a beverage like chips and pretzels so it is hard.
I know that Dr Atkins says not to count tea but he also says that green tea aids weight loss. My new trick is to mix bags of green tea with a few bags of black tea and add splenda and maybe some lemon juice. It is a home brew but gets me drinking water. It is probably much healthier than cool aid overall.
Back when I was eating carbs I used to drink a gallon of water a day, now I stuggle to drink a quart ! Having an ice cold brita helps a lot because it makes the water taste better.
