"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."
