Anyone tried it, what do you think?

I'm not sure if it works... it says to drink it with 4-6 ounces of water... which really isn't much water. I'm wondering if anyone actually follows the directions on the packet.

Also, what flavors do you like? I tried Lemon-Lime because that's all they had and it's pretty good. I also tried Raspberry and that was kinda nasty, and I usually LIKE raspberry!
