Night sweats?

These night sweats are killing me. I freeze all day. It doesn't matter how much clothes or blankets I have.. It's like my blood it cold. My iron is good.. No fever. At night I've tried sleeping naked, bundled and in light clothes and at least once a nice I wake up drenched in sweat and freezing.. Like I get so cold I want to take a hot bath!! Idk is there any remidies to help? I hate it I can't sleep and be warm!!!
