Hi Yes I can relate to the heat issues. Once I get into cooler air I'm better. I too wake up in the middle of the night if I get hot.
What I normally do is keep my house temp at 70. If it gets cold I can add more clothes or grab a throw. I keep a fan next to my bed if I end up getting hot. Also they have cooling vest that you can purchase to help in situations like that. Think about getting on so you can enjoy company.
