I need a better substitute for soda.
Try Fruit2O it comes in packages of 24 bottles with 4 different flavors.
I do tea also but if you need the fizz you can buy a soda stream and make your own soda and believe they have flavors that have sugar substitutes.
Honestly it is called water and nothing is as refreshing or as good for you.
Right now I drink Fruit two O I don't really know if is any good for someone at all. WWW.FRUIT20.COM
You can always try stivia it a natural sweetner.
