Also, just to be clear... I'm not suggesting that diet soda is exactly good for you. I plan to try and wean myself off of that as well, over time. But the sugar (HFCS really) in plain soda is just horrible, horrible, evil stuff... especially when it's in soda, since sugar that comes into your body in such a ready to digest form seems to hit your bloodstream much faster than, say, a piece of orange, which also has plenty of sugar (fructose) but has to be digested to get to the sugar.
And there's a lot more sugar in a soda than in a piece of fruit. (although fruit juices have a lot of sugar, which is why people suggest that you drink small amounts or water it down.)
A 3" orange has about 14 g of sugar.
12 oz (a 355 ml can) of coca cola has 39 g of sugar.
