I use unjury brand Protein drink. chocolate splendor is the one I am able to tolerate the best. It tastes like chocolate milk/nesquick. I mix it with 8 oz of skim milk. It has about 20gms of protein. I have 2 of these a day. I'm not sure where you are at since surgery, or what your program calls for, but I am to have between 70-90 gms of protein daily. Low-fat cottage cheese was and still is a friend. Soft scrambled eggs, Baby food meat with a little low fat mayo, light artifcially sweetened yogurt.
Hope this helps. I wouldn't have gotten through without this Protein Drink. I have tried others, and just couldn't do it.
Everyday will get easier..
