Out of desperation, I tried INUSpheresis in Frankfurt recently. The treatment itself cost almost $6000, plus the travel. I had two sessions, with two days between them. I felt normal (not sick) after the first treatment, and this continued for three days - that is, though my return to the U.S. Since then, my ME/CFS symptoms have been worse than before I left. This downturn is possibly due to an infection, but the upshot is that the apheresis didn't improve me durably enough for me to try it again. (However, it was nice to feel okay for a few days!)I
