Yes, that's precisely. what I had in mind when I posted that.
CFS and ME are synonymous, BTW, CFS is the more American term, and ME the more "British".
And, yeah, having now had both, I suspect that LC and ME/CFS are likely the same syndrome. Of course, I might be a little subjective here.

It's a bit discouraging (and baffling) though, that with DECADES of research on CFS, no definitive treatment has been found.
