I tried the green ones (lemon/lime) today. Very tasty. Can't really say whether they powered me up, but I guess they work the same as any sugar/salt/potassium tablet would do, consumed together with water. Or like eating Gatorade or cytomax powder and drinking the water separately -- only not so messy .

I happen to have two packets of orange left. Guy in the store said they taste like orange creamsicles. Does that sound tempting, or would you rather have blueberry, or lemon/lime, or tropical fruit punch flavor? I need to get some more anyway and can hit the store tomorrow.
