Protein protien protien

My surgery is tomorrow and I still have purchased protein. I atte.pted to today buy went crazy with all the options. I plan to(sending my spouse) buy the protien at wall mart or GNC pleaseeeee any recommendations. Not big on the milky shakes! Is protein powder is some 0 calorie drinks sufficient??? 

I use About Time products, found at GNC. 

Syntrax Nectar comes in lots of fruit-based flavors that you can mix with water, 0 calorie drinks such as Vitamin Water Zero, etc. I believe that GNC carries them. I know at my Vitamin Shoppe you can buy individual packets to test as samples before committing to a larger purchase. The numbers on Syntrax Nectar are excellent, too, in terms of calories, carbs, and protein.

I use unflavored Isopure from GNC. I have heard great things about Syntrax though but have not tried yet. Isopure also has these clear drinks too at GNC. I haven't tried those though. 

Everyone has such different tastes in protein and immediately after surgery your taste buds may change as well. I would recommend buying from GNC as they will allow you to return protein powder that has already been opened if you don't like it. A lot of people like the Premier RTDs and Syntrax flavors. You may want to give those a try.
