Not gonna lie, it is hard. After surgery, your taste buds will probably change anyway. Everyone says to get the unflavored unjury and add it to Soup and shakes. I haven't tried it but I drink the Muscle Milk. It isn't as bad to me as some of the others. They have some Isopure drinks at GNC that are in glass bottles kind of like Gatorade. They are Clear liquids. I have tried the apple melon and it is good. That may be an option. I think it has 20 grams Protein. Good luck!
