(Sorry I haven't read the whole thread here.)
I've used some of the DIY Perrin techniques and noticed improvement.
For years (probably 10, and I've had CFS for 26 years) generally in both Autumn and Spring the glands in my neck get very swollen, and this seems to put pressure on the base of my skull making me feel like I've been hit about the head with a baseball bat. I get ringing in my ears and extra noise and light sensitivity. On top of the usual CFS stuff, this has always made me miserable...and it's gone on for weeks!
Last year I tried a couple of the drainage techniques detailled in the book...and while I was waiting for the book Tom kindly got me started on the basics with alternating hot and cold pack.
It worked
for me, on those particular symptoms. I wasn't expecting a cure...but to have relief from the horrible pressure and associated stuff in a few days rather than weeks makes it worthwhile for me.
I like the Perrin Guy too, get a good feeling about his motivations
