"i started taking ms contin 60mg this week. i was taking methadone 120 mg a day for over 5 years.  i am having some trouble with the changeover, but after 3 days i am getting better.  i also take oxycodone 15mg up to 4x a day for pain. my doctor started me on 60 mg 2 x a day, then told me to double it. still having some trouble with the withdrawals from methadone but i hope this will work. so far it&#039;s okay. i am being treated for chronic pain from a lamenectomy and spinal fusion without hardware (failed back syndrome)."
