I had surgery on the 20th. I have been very fortunate, no vomiting at all for me. (Knock on wood). The one thing I really made sure to do was take things slow. Yes, you want your proteins, but they will do you no good if you don't hold them down. I didn't have anything but broth and water for three days. Then I slowly added a few oz of protein shakes and just did a little more each day. I am now up to 5-6 two oz meals a day. Keep up the good work. You will a get understanding of what your body us telling you in no time.
