Is flavored water the same as non flavorved water???
Be careful on certain flavored waters. Some carry a lot of sugars, calories and such. You can buy the squeeze drips for your water and those are about 10 calories per drop. Makes it taste great!
I like zero calorie flavored sparkling water, or water with a splash of lemon. I don't do vitamin waters our any of those things that are packed with flavor though, just something mild with less chemicals and sweeteners. Zero calorie sparkling is definitely not the "same" as plain water since it had some additives, but close enough for my standards of health these days and a personal improvement over sodas of any variety.
You can get get a kit to make your own sparkling water. That way you can make it from pure water and be sure whatever you add is fresh and safe... Maybe a splash of your favorite store-bought 100% juice, or make your own juice at home... Minimal sugar and it's all natural fruit sugar, just enough to spike that water's flavor up a notch.
