I have a "suspicion" about RSD.
I think it "turns on" our adrenal glands, inappropriately.

Sometimes, I lay down, (I only have a love seat to sleep on, but, it's OK, with the cpap) keeps me from tossin' around. anyway, soon as I lay down, my eyes just pop open!

It's as if I'm so "looking forward" to sleeping, that I get excited, and can't do it!

I think RSD plays tricks with many of our glands, and therefore we get as messed up as we do.
And, our poor doctors, really don't know what to do, except "treat the symptoms".

And, we're ALL Different!

But, over time, we all seem to get on a "cocktail" of some sort... for our "Array of Problems".

Just a few thoughts.
