I was sleeping in sweat pants last night and I was so hot I kept waking up and then taking off the blanket and then getting cold. This went on all night. Finally around 2 or 3 or something I took off my sweat pants and just slept in my Fruit Of The Looms. I know thats kinda weird but I got instant relief and I was able to sleep comfortably under my Wizard Of Oz throw blanket.
