Good advice from all. Had the operation twice as the thymoma came back four years after it was removed the first time. I myself spent a lot of time in the recliner but could not wait to spend the night in my bed. If you can make yourself comfortable propped up in bed you will be better off. Also walks during the day were very helpful for me. Broke up the day and tires you a bit so you are able to sleep better. Stopped the pain meds during the day as soon as I could and just used them for sleep or if I was uncomfortable. Do what feels right for you. Wishing you the best.
