My auntie and two of my friends have ME. One of them got an expensive treatment for it (which at the time at least was not verified as to whether it really works), he says he feels better. But, I dunno...
Why I know three ME sufferers and you know none, I dunno. I thought it was quite common. I know several people with chronic fatigue and other such conditions where things like tiredness and pain are symptoms. Quite used to them just falling asleep all the time and such, bless.
