I had 3 buddies that lived in an old two story while they were in college. One weekend when one of them was not there the other two had a huge party. I was not feeling well but went anyway. As the night went on, I was feeling worse and worse. Uncontrollable freezing shakes etc. I went upstairs to my buddies room (who was not there) and crawled in to his heated water bed just to try to warm up.
I woke up 16 hours later feeling like a million bucks. Nobody had any idea I was still there. haha
