I run several fans at night to take care of incidental "night noises". I, too, run the tv on bad pain nights. I have several shows that bore the socks off of me and I fall asleep as soon as the intro. music begins. Long live classical conditioning. I have a an old tape that has six hours of one show. I just pop the tape in my old tape player and I am good to go. If I just play one episode, I wake up as the show ends. Go figure.
