Because my work comp company is no longer paying for my Kadian I have taken daily since 2000 my physician had me stop taking it suddenly! He had me try the generic but it kept me awake all night. So I stop that also. Now I have Norco to take every 4-6 hours. I am feeling the affects of stopping the Kadian after so many years and stopping it suddenly! I sure hope the cold chills, diarrhea, and other stuff will stop soon! I know now a patient should never stop a morphine derivative like Kadian suddenly! Just trying to help my fellow chronic pain patients mine due to a work injury.
