So last weekend at Target, one of my favorite all time stores, they had their brand of Crystal Light "On the Go" packets. I decided to purchase these because of course they were on sale! Well today I brought my water bottle, cold from the refrigerator and dumped the packet in the bottle. I screwed the top back on the bottle and shook it. It is the best thing ever! Crystal Light is one of my favorite 0 calorie drinks...it's GREAT...you should try it if you haven't already!
