WOW, I'm so sorry you are suffering so much. Have you read about the newer treatments? The neridonate (sp) is showing hugely positive results in many patients. I don't know if that is something you can get down there. What about Ketamine?
My doc just put me on buprenorphine which, along with the lamictal and cymbalta, is keeping things more reasonable (though I hear you on the breeze from AC/fan ouch!). Most docs don't do buprenorphine, none of my previous docs even MENTIONED it.
