My fibromyalgia has been much better since surgery. I did have a lot of trouble sleeping at first, but it got better after a couple months. I've even been cutting my Ambien in half. Still occasionally wake up in the middle of the night, but usually can't get back to sleep if I'm hungry, so keep protein shakes to have if needed. Otherwise have gone back to naproxen instead of stronger NSAIDS & off gabapentin & plaquinal. Only take other pain meds every other week or so. I also have RA & back problems. Feeling so much better. 4 months out.
