I'm right with you. Pre-op, down 50lbs. Gained 10 in hospital (!), now I'm 16 days out and lost 17. Mind you, 10 of that was hospital fluids. I just met with my surgeon yesterday, and it seems to be a combination of water and calories. I have been pretty short on both. On the full liquids I had only been getting in 300-400 calories per day, and was always short on my water. I am now on pureed, and I am going to try harder on the water and getting in more calories. Hopefully that will kick start something.
