Quetiapine
"I have crps I developed after 2 major shoulder and bicep surgeries in less then 3 months.  I am on fentanyl patches,  oxycodone, topamax, baclofen and cymbalta for pain.  I was taking ambien at night to sleep.  It was giving me 4 hours of restful peaceful sleep if i did not move.  ( Moving my shoulder causes severe pain). Dr. was concerned about the sleep walking caused by ambien.  She wanted me to try this I have had horrible nights, a terrible drugged feeling.  I am aware the world exists all hours of the night.   It is causing headaches in my front forehead area.  The headache hangs on till well after lunch most days.  I actually decided last night I would rather deal with my pain 24 hours a day with no relief then deal with the effects."
