What should I be eating?? I get hungry...I am up 3 lbs... I an freaked out!

You should be "eating" whatever your doctor told you to eat. Mine had me on liquids for the first week after surgery. Sip, Sip, Sip. I can't say it enough that you should be concentrating on getting Water into your body and walking. Moving eliminates gas pain, helps your body recover without getting clots, and helps the weight loss by making your body work. If you haven't had a BM yet, walking will help that process LOTS.

Protein shakes, K2O Vitamin water (with protein) and whatever other stuff your doctor said you can have. Worry more about the water than the protein and try to get in the amount of water the doc prescribed. Mine says 64 oz of water a day and 70 grams of protein.
