I was banded on the 17th Dec also. I stayed in the hospital overnight though. I experienced ALL your symptoms. Take a liquid painkiller, sip water, juices etc. I ate soups for dinner but only could stomach 1/4 of the bowl at any one time. Yesterday (Dec 21st) was the first day I started feeling better. Today I spent 4 hours Christmas shopping. I made time to get a massage in between but informed them of my operation. From day one, my husband massaged me which provided some relief. Take a liquid to relieve your gas and walk around the house. That's what I did for 4 days. The pain will eventually go away. I had no appetite whatsoever but kept sipping as much as I could. Now I'm only in pain around my incisions when I cough or sneeze. Other than that, I'm feeling so much better. I'm still struggling to eat enough though. I'm drinking protein shakes, juices, water and soups for now. I have lost 16.5 lb since my pre op diet. Hang in there. It'll all pass! Good luck!
