Im still on my 3 week post op, but my good friend who is 2yrs in, gave me a product that might help you. Its a 1 oz jellow shot that is 15g of protein and 1 serving of fruit in each cup. Its made by Protica. Its called Protein Twist in orange flavor. This might help with being only 1oz and 15g of protein. They have other flavors too. If you Google it, you can purchase online. Zero sugar and fat only 100 Calories.
