Isopure!!! I go to the health market and buy 7 of them every Sunday. This drink comes in several different flavors (ice tea, grape, orange and many more) theru have 40 grams of protien, so by the time you drink one of those (make sure it's throughout the day, not all at once) and eat your meals you shouldn't have a problem. There are also "protien bullitts out there they have like 54 grams of protien and you can drink it in 2 big sips) The days I have that I take one gulp in the am and one in the afternoon.
