I wanted to mention... there is a company in MASS called Polar Beverages. If you can find it, they make seltzer water with NO artificial sweetener, no cals, no sugar, no anything. They makes TONS of flavors and its soooo good. Blueberry, Pomegrante, Grapefruit, Vanilla, Lemon, Lime, Cranberry Lime, Raspberry Lime, etc... they are always coming out with the latest 'craze' fruit flavor.
I hardly drink soda at all. If I want a rum & coke at home I use Coke Zero but only drink one can maybe once every 2 weeks. Maybe 4x a year I get a sunkist. (mmm my fav) but all artifical sweeteners are just not good for you.
I used to drink Fruit2O (a fruit flavored water) but it contains aspertame. So I gave that up.
