Hello.  I just read your message and am in a similar position.  I too can't
sleep or wake up after only 2 to 3 hours of sleep.  Everything is supposedly
normal but I can't sleep.  Though I have hashimoto's thyroiditis, the
endocrinologist claims my thyroid is not affected.  I've been MRI'd, CAT
scanned, psychoanalyzed; I don't know what all but nothing turns up.  I can
barely work, have thought of quitting my job, am really getting discouraged.
 What is this armour you talk about here?

Marcia
