It's hard to give up the black oil, er, soda. I don't really like plain water. I can't take anything with most artificial sweeteners, they are migraine triggers for me. I bought a SodaStream, a 10 lb. bottle of CO2 and a few BiB syrup cases of Barq's Root Beer and have been lowering the concentration of syrup the past few months. I'm down to 1/4 the normal concentration of syrup. Eventually, I should be acclimated to the taste of fizzy water by itself... still not much of a fan.

There are several brands of flavored soda beverages that don't have any sweeteners, sugar or artificial. LaCroix is one of them.

The taste has been described as being "like sitting next to someone who is thinking about drinking an orange soda/root beer/etc."

Carbonated water plus orange or lemon peel is great!
