It's been a week since my surgery and every single night I've had horrible nightmares (I rarely have any type of scary dreams). If I wake up in the night during one of these nightmares, I sit up in bed and dread going back to sleep. It's so strange. I've been taking Flexaril 5mg 3x day and Percocet or Norco as needed for pain. I don't know what is causing this, I feel so strange and afraid to go to sleep tonight! I thought at first it was due to the anesthetic, but that has to be out of my system by now, right?? I can't remember ever having nightmares like this for so many nights in a row. I guess maybe I was more stressed out about the surgery than I realized! Crazy old Hermitlady!!! Anybody have this happen to them from meds?
