Rotten CPAP machine. I thought I'd had a good night's sleep last night but I feel blinkin' terrible today - headache, all over aches, knackered, just like I'd never made any attempt to get the CFS under control.
I have vowed to give this a month's trial, and I will, and I will do the sleep study to see if it's working. But I've got to start feeling better than this, I can't sumon the energy to do anything except play on the computer and I have mounds of schoolwork waiting to be done, to say nothing of the clean washing that is taking over the house! (And the dirty washing, too, for that matter).
