Last month. My personal experience with KDM is that he wants to do something for his patients, and he suggests things even though he knows they have little chance to work. I think it is because he does not want his patients to despair. Some doctors believe that if a patient is busy with a protocol, then he has hope and this is a positive thing. Many patients cannot stand the idea there is no treatment, they just want to try whatever the cost. Some people amalgamate the idea of "no treatment" with the concept of "no disease", which is of course incorrect. For the moment, the mood is very much "chronic Lyme"; 15 years ago it was mycoplasms. Two years ago, there was reports of massive improvement with Rituximab. Well, now it appears that people getting really better are the exceptions rather than the norm. In fact, it seems many patients actually got worse. Antibiotics seem to follow the same pattern. That might be an indication that a break is necessary. Discuss the issue with your doctor.
