Thanks for reading and replying, mrsD. I hope you would. With your knowledge on the subject, you've been helping me since before I joined neurotalk. It feels like I'm talking with a rock star! Regardless, this is no fun to have. I can't imagine having it for many years / decades / rest of my life.

I'm currently being driven by "there always is a cause; it's just a matter of finding it." I just hope medical science is advanced enough to decipher it.
