I lean toward the theory of there being multiple diseases lumped in the CFS/ME category.
The breakthrough that explained why pernicious anemia patients couldn't absorb B12 came because a doctor experimented to prove that intrinsic factor exists. His experiment involved eating liver, throwing it back up, and feeding that to his patients (who did not know what they were getting). The patients were able to absorb the B12 from the regurgitated liver because the doctor's intrinsic factor was part of the mix. The experiment would be considered unethical today, but it was considered a breakthrough at the time.
