I drink a half a gallon to a gallon of water during the day and training. However, in the evening I drink diet soda like I am trying to win a contest (prob a 2l bottle a night). Just love it, always have.
I have been on a bit of a healthier kick. Just don't want to put all those extra chemicals in my body everyday. So today I got a bottle of sodium free club soda, a lemon, and some stevia. I know it can be argued that stevia is not natural because of how it is extracted, but it's certainly closer to natural than artificial sweeteners.
I am pleased to say it is a really good alternative. In addition, adding lemon into my diet is good for a number of reasons. I may just have kicked the habit.
