Both, if I drink it at all, it rusts the pipes you know!!! LOL Really, I drink mine with a little raspberry flavor.
Mostly Plain, but I sometimes have flavored water instead of a soda.
Just plain water for me.
I like plain water.. I mean its natural :P
I like plain old water best
I like the mandarin orange Propel. It kind of tastes like a creme cicle.
I love the grape vitamin water, or plain water with a squirt of lemon in it.
Definitely flavored water. I only drink water when there is absolutely nothing else to drink.
I like flavored water, but it is healthier to go plain so I usually go with plain unless in a long car ride!
I accidentally bought a flavored water when they first came out. After spitting out the first mouthful, I threw it away and bought a plain.
