With the percent of overweight people rising dramatically, it is increasingly important to watch one's diet. The number of sugar drinks on the market is astounding, so I searched for a drink that was very low in calories but still delicious. After trying a few different powdered drink mixes, I discovered Crystal Light Energy Wild Strawberry. I carry around a box with me everywhere! You just pour the powder into a 16 oz water bottle, shake, and enjoy! It only has 5 calories per packet, so you don't have to worry about ruining your diet. It contains 60 mg of caffiene (about the same as a soda)--you can get your caffiene fix without staining your teeth. The sugar substitute used is aspartame (the same as in sodas), and there is some concern about the side affects; I don't have any problems, but if you know you're sensitive to it or are worried about using it, then you probably shouldn't use it. For most people, however, it is not a problem. I drink this all the time, and it has certainly aided my efforts in preventing weight gain.
