This is strange because I always used to be colder than everyone else before I started using BTD/SWAMI. I HAD to wear socks to bed, even with an electric blanket on, because my feet would feel so cold that I couldn't sleep. Now, I don't even use the electric blanket at all except to maybe warm the bed ahead of time if I feel cold. In the morning when I wake up, I am warm and sweaty. This NEVER happened before - even as a child I always felt cold in bed.

...viral syndromes cause night sweats.

This explains some of mine as well...  I just had a long bout of clearing virus activity out of my sinuses...  I was sweating all the time, not just at night...

Night sweats are not to be confused with waking sweating by any means.  When your body is in a resting state, sweating is a signal the body is working excessively hard for some reason or another.

I was reading about hypoglycemia.  It seems that the shakiness, sweating, and clammy/cool skin could all be attributed to the action of adrenaline, which is released along with cortisol to help raise blood sugar.  FWIW.
