"after suffering a back injury and having two surgeries, i have had chronic back pain for the last 10 years. i have used many narcotics to try to relieve the pain including hydrocodone, percocet, vicodin, demerol, morphine, darvocet and oxycontin.  none of these worked for my pain and i thought i would just have to live with it.  then i tried methadone.  i could not believe the way i feel since changing to it.  i have almost no pain anymore and can function relatively normal again with no side effects at all.  i have been on the same dose for the last 6 years and don&#039;t foresee it changing any time soon.  methadone is the best pain reliever there is as far as i am concerned."
