Yes, i did it with one of the best FMT clinics in the world in Sydney. Sadly i didnt get any noticeable benefits, however im still a firm believer in the theory as the evidence keeps building for it being a strong link to many auto immune diseases + anxiety/depression (there is so much positive data in germ free mice). The problem with current technology is that bad flora is embedded into the intestinal mucosal layer and FMT may not take hold strongly enough to clear these guys out. The clinic was working on a more thorough strategy to eliminate flora remaining before application of FMT. Ive decided to wait a few more years, and come back to it when the science and processes have progressed. In the mean time ive chipping away at every other possible diagnosis, kidneys, MS, lupus, thyroid, iron. Im now back to looking at my sleep which is fragmented as hell.
