Ugh. Sounds like you really need relief as sleep is important to the healing process. I was thinking asking your doc or calling in to their medical assistant and asking if gabapentin makes sense to prescribe in addition to what you are already on.
I did try Lyrica prior to my lumbar fusion but after a laminectomy/ microdiscectomy and it messed with my mind too much. Maybe I didn’t give myself enough time to get used to it but I went off.
Hope you get some help from your doc. Sometimes you need to be the squeaky wheel with them to get the help you need.
