I hate to derail it, but everyone in this thread is right:
Drinking distilled water is bad for you, especially for your teeth. Your teeth will not get the minerals and will eventually weaken. You need to drink water with something in it. Also the minerals in the water are what give it its taste: there is natural spring water from Spain that almost tastes like saltwater because of the minerals in it. (if you want this, try the brand Vichi Catalan)
I would know, my grandpa sells fine imported bottled waters. (of course, if you want to buy some, let me know.

)
