So sorry you are feeling bad. But as others have said, hang in there. On my 5th day after surgery I thought I'd never feel good again. Then I woke up the next day feeling sooo much better - just literally overnight!
The heating pad on my left shoulder really helped. Also, I really didn't want much food, but drank lots of juice and soup/broth. V8 makes a squash soup that I really liked, and the flavor satisfied me.
Good luck!
