I first came across these when I was out on the road performing on a national tour. I normally just try to drink water, that way I don't spend much on beverages, but these we given to us in our green room. I tried one cause I thought it was a great alternative for a flavored drink for not a lot of calories. I was hooked! I ended up hoarding a lot and used them continuously on the road. They have many flavors, but I really enjoyed Green Tea Raspberry. It's not too sweet, but yet sweet enough to make the green tea not be dull. Cause I normally can't handle green tea by itself. I'm just not a fan of that flavor and that's a shame cause Green Tea has great health benefits, which is why I was drawn to this flavor! It's so easy to use. I used a bottle of water and dumped in the package, shook it up, and it was ready to go! Its such a convenience, especially being on the road or in a hurry, cause I didn't have time to make a whole pitcher or even one glass. So easy to dump in a water bottle and go!
