Heard of Special K20 Protein Water?
I just found this at WalMart and decided to try some. It is 16 oz and has 5 grams of protein. Not as much as the Isopure, but cheaper and tastes better! So far I have only tried the Lemon Twist, but they also had Tripical Blend and Strawberry Kiwi. It is 50 cal., 8g. sugar & 8 g. carbs. Not perfect, but easy to get down with no after taste!
