Remember too, if you had difficulty sleeping before your surgery, you will after! I'm over three months post-op with both knees and find that I toss and turn. If my knees get comfortable, sooner or later, the hips get tired of being in that one position so it's roll over yet again. But sleep aids don't help me either so I keep a CD player by my night stand and play some soft, relaxing spa music. I might need to do this three or so times during the night but always go back to sleep within a song or two. Have never heard the CD from start to finish!
I've never tried Percocet, but did try Ambien-CR and found that didn't help. The possible side-effects scared me so bad that I put up the baby gate so I didn't take a tumble down the stairs!! Nothing, not even an interesting side-effect.
Hope that one night soon you get a restful peaceful night, but don't feel at all guilty if you need a cat nap mid-day to get you through. Just try not to nap too close to your bedtime. Good luck!
