So are you on Phenobarbitol? I've heard of it being used for migrane sufferers and RSD victims. If so, Phenobarbitol is a controlled substance and it does have some mind-altering effects, though not as severe as opioids (Morphine, Dilaudid, Demerol, etc).
My specialty is trauma, renal, endrocrine and cardiac - very little neurological or psych in my 15 year background, so my knowledge of RSD is very limited. I do know a former nurse who was recently fitted with an internal neural stimulator with insertions at C5 and T1 - she says that it has made her life livable, but it is not working as well as she hoped.
Do you have a website up about your trials and tribulations with this disease? If not, consider making one - others may be able to use it as a point of information to help them with their afflictions.
My wife has end-stage MS, complete with the peripheral neuropathy, optic neuropathy, loss of fine motor control, neurogenic bladder and is now confined to a wheelchair and it is a race between the aspiration pneumonia or urosepsis that will take her to the celestial chariot.
