Hmmm. I guess we know why your ready to eat that couch! There are so many variations of the post op diet it's hard to know which one is the best. I hope it gets easier for you.
I'm also 3 weeks post op. I know what you mean about not knowing if your full. With that said, I am feeling hungry at all. Are you getting enough protein in right now? I try and get a close as I can an that seems to help.
