I went to see Dr. Boyle today in Dayton because my sensitivities have developed to the point where it is impossible for me to stay in Ohio -- even living outside in a tent -- and on my travels west last month I found I got sick whenever I went into buildings. He recommended a series of shots known in the US as LDA and in the UK and Canada as EPD. I've been reading about these and have found the following links. http://en.wikipedia.org/wiki/Enzyme_potentiated_desensitization On Dr. Myhills site http://www.drmyhill.co.uk/wiki/Enzyme_Potentiated_Desensitisation_(EPD)_-_how_it_works http://www.epd.org.uk/useful-links.html from Friends of EPD, a UK organization of patients Dr. Boyle says these shots are "the only thing that will help someone with as many sensitivities as you have." He says the US study was closed down by the FDA because traditional allergists opposed something that was cheap and effective and would cut into their income. Dr Myhill also writes enthusiastically about it for her ME patients. I am reluctant to get into another expensive, although I am also intrigued at the prospect of doing something to quiet down my reactive system in addition to moving to a drier climate and would like to hear from people who've tried it or are trying it now. If I do it, I will not work with Dr. boyle because I don't want to have to travel backk to Ohio every two months. Not sure where I'll go though.
