switch to diet.
tastes exactly the same. don't be a poon and think it doesn't. it does.
or just man up, and realize you are a ****ing 32 year old. you don't need to be sitting around slamming sodas.
also, 64oz of water is nothing. I drink half that before I shower in the morning.
you're not actually addicted to soda. if anything, you have a minor caffeine addiction. have a cup of coffee or tea or something instead.
