This is at a bit of a tangent to the post, but do you mind if I ask a CFS-question (or three) Sophie? (Feel free to ignore if it's not something you feel like answering.)

I was just thinking about mostly-physical activities versus mostly-intellectual activities and wondering to what extent the CFS affects the latter in your experience. Do thinking activities contribute to the fatigue too? And has the experience of CFS in any way changed your intellectual processes?
