"i have had rsd (reflex sympathetic dystrophy) now for 8 years.  after being diagnosed with rsd, i was given methadone.  it gave me my life back without making me feel &#039;buzzed&#039;.  i also haven&#039;t had to increase my dosage over the years.  you don&#039;t develop tolerances with this like you would with the other narcotics. for those who need it - it does the job."
