Daylilyfan, When i was on methadone that was one problem i didnt have but when i was on kadian, or oxycontin i had the same problem. Dr gave me a prescription for amitiza(for chronic constipation) once a day. Sorry to hear about the methadone not working as well as you hoped. I am the same way- when i was in a major flare i was taking methadone and once it calmed down some I was switched back to oxycontin. I told the Dr. the same- that i wanted to save the best for when it was out of control (i have fears of coming a time when nothing will help) momof4
