Have you gone primal but miss the fizzy from soda? I do, sort of. I had already weaned myself from soda except for one glass of Dr. Pepper, usually everyday.
(I am a water drinker except for coffee in the mornings. I do drink hot teas in the winter or in the evenings if I get cravings.)
We went to our local Trader Joe's on Sunday. I got a bottle of Trader Joe's Sparkling Natural Spring Water. I made an orange "soda" with it. I filled a glass about a 1/4 full with OJ and then topped it off with the sparkling water. It's very good and filled that fizzy craving I had! I wasn't jonesing for sugar afterward!
You could use any juice or even some of the Strawberry Kiwi Sauce to make this "soda".
