I Break Out In A Sweat Similar To That When

I break out in a sweat similar to that when a fever breaks. It is accompanied by light nausea and
weakness. Other times I'm fine. I sweat in any normal indoor temperature that others find comfortable.
I am awakened at night by the feeling of warmness and have to get up until my pillow and bed cool
down from my heat. I rarely feel cold even when I'm outside in the winter with no coat. Tests show
my thyroid to be normal -not even close to out of range. Other blood tests for sugar etc also good.
