When the cherry pomegranate flavor of Crystal Light On The Go Immunity came out, it was all the craze at my mom's work. They were all drinking it like mad and I'm sure that Crystal Light made a ton of money off of them. These single serve, toss in a bottle of water packets, they are the bomb. I try to drink lots of water, but sometimes I just get so bored with plain old unflavored water. I am also lazy and didn't like to make up 2 quarts of stuff every time. Plus I like the portability of a bottle of water. When I'm tired of drinking plain water, I toss in a packet of Crystal Light and I will drink a lot more liquid. I'm personally a huge fan of the Cherry Pomegranate but be careful not to spill. It's a dark red color and stains like mad! If you spill the powder on the counter, or on your wet hands, be prepared for a red stain. Fortunately, any of the antibacterial kitchen cleaners will usually get out the stain.
