"i have been taking kadian for about two years and it has been the only medicine that can manage my chronic pain. i was also taking several vicodin daily prior to the use of kadian.  now i only take a vicodin once in a while. i also have an implant in my spine for pain control but need kadian as well.  i take 30mg once a day, at night.  when i don&#039;t take this medicine, i can not walk without a cane, so it also helps my mobility."
