Lol, nah, never tried drinking pure Mio. All the flavors I've tried are really good. I saw the energy ones today and decided to give them a shot since they have no calories/fat/sugar just like the other Mio's. You can put a lot or a little of the stuff in your water, depending on what you like. It's a great alternative to soda and it helps keep water from getting boring to drink all the time.
