EH - your want to keep yourself busy with books, movies, scrapbooking - whatever you need to do to keep your sanity.
Ask to go to PT ASAP. The PT should be able to give you exercises to do right away after surgery. Often, riding a stationary bike is one of the early exercises. Many of my patients end up with an hours worth of exercises to do twice per day. So rest assured, you will have things to do.
I hope your surgery went well. If you would like, post the specifics of what happened with the surgery and I might be able to give more suggestions.
Living life like there's no tomorrow.
