I also had surgery Aug. 12th. Was 296 day of surg. Am 282 5 days post op. Yesterday I felt physical hunger for the first time. This morning, I drank 4 oz of RTD whey protein shake and later ate 2 small bites of plain soft scrambled egg. My surgeon is Dr. Clayton Frenzel and he recommended Isopure flavored protein drink from GNC for my clear liquid stage. they come in many flavors but are all considered a clear liquid , I bought the grape, tastes like a non- salty watered down Gatorade drink. I usually add about 4 to 8 oz to my ice and water(I have a 32oz drinking cup) and sip it all day. each serving is 40g of protein. They are big bottles , so you can get atleast 2 servings out of each. fellow Aug. 12ers....
