These things are fantastic!!! I'm a big believer in drinking just plain water, but once in a while, I really, really need a little something extra. These are perfect! I use one packet with 32 ounces of water (should be used with 16 ounces) and they add just enough flavor. The stats (for the strawberry banana, but I think the others are close, if not the same):
0 g fat
6 g carbs (5 g fiber)
3 g protein
I only buy them when they are on sale. There are only 7 packets in a box, and Food Lion has them for 2/$5 on sale. Have a coupon you want to get rid of? Let me know!
