Thanks anncavan and heapsreal. I'm not sure what to think. It sounds like I really should get a lymphocytes test. I know that for the first 4-ish years of CFS, my glands were always substantially enlarged, but over the last few years, they've felt more normal (although I don't actually know what normal is!). Also I don't know if I fit into any of those categories, heapsreal. Early on I was definitely the tired but wired type, but year by year I learned to accept more and more that I need to rest more and more, not just when I have flares, but all the time (on and off), not just push through with another coffee. Although I've never heard of the 'sleep all day' kind of CFS patient. I thought everyone was like me: fatigued and brain fogged, but not particularly sleepy. I'm usually the type to catch eveything that comes along though.
