So 7-up is really impressing me lately. Sure, the soda isn't as good as 100% sugar stuff, but it aint bad and it's not near as bad for you as regular soda or aspertame.
The three flavors of 7-up plus (it has 15% of your recommended calcium in it!) are Berry, Cherry, and Tropical Fruit (pineapple mango I believe). They are yummy...but Berry just doesn't do it for me. I totally dig the pineapple mixed one. :)
