Okay, CECD is an interesting suggestion that I hadn't heard of, but how would I have gone from having no trace of it in early March 2010 to having a bad case of it in April? In contrast, the onset of (this kind of) CFS is so frequently observed to coincide with a flu-like illness that it is also called Post-Viral Fatigue Syndrome.

But I do agree that's it's highly plausible, indeed very likely, that inflammation plays a role.

I suppose I could get a medical marijuana prescription, but that really doesn't appeal to me. My case is relatively mild anyway, I gather, compared to some of the nightmare stories I have read.
