XXX vitamin water is the best
I used to be a fat kid, then I stopped drinking soda and lost something like 20-30 pounds over the course of 2 years. I'm still incredibly lazy and out of shape, but now I'm not fat.
Soda is terrible.
But so delicious, sigh.
I have a can of Dr. Pepper sitting on my desk right now. I feel like one of those people who quit smoking and carry a cigarette around to say "NO I WONT SMOKE YOU", but it's so tempting.
Like I said before, this is exactly what happened to me. I'm starting to go to the gym now though to lose the remaining 10-20 lbs to my goal, and then working on getting in better shape. I'm one of the few people from my high school class who actually lost weight in the 5 years since graduation.
