"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 'buzzed'.  I also haven't had to increase my dosage over the years.  You don't develop tolerances with this like you would with the other narcotics. For those who need it - it does the job."
