Not sure about this doc, it is not up to you to find a working treatment - that's his job! I take it that you have been on this regime since the diagnosis? If you have not actually improved on this then I would say you need to go back to the doc and say that something else needs to sorted, if he still is not willing to be helpful that perhaps you need to get to see another doc. Personally I would have thought it is best to treat the actual disease, if this gets under control then the symptoms don't happen surely.
