I stopped drink soda and started drinking flavored water, but the flavored water is carbonated water! Is carbonated water bad for you?

Carbonation OK. Carbonation in reasonable quantities is not known to cause disease. It is wise to be aware of what else is in what you are drinking. Recommend looking at the ingredient list and the nutrition label. .
Bubbles. Carbonated water is drunk by billions of people around the world. No. It is not unhealthy.
