What are you expecting from a FMD? If you're hoping for expertly prescribed treatment for ME, you're out of luck, because no one knows how to correctly prescribe anything for ME. We all respond differently, and what works for one person doesn't work for most, and makes at least a few people worse. I doubt that any ME expert can choose treatments more successfully than random selection from lists here.
You might have better luck looking for an IBS expert without limiting your choices to ones that also 'specialize in ME'. I'm assuming that IBS specialists can actually help with IBS.
