I also had a neurotic cat that sat on my face while I was sleeping and ran marathons around the house. After a few squirts with a water bottle, she stopped sitting on my face and learned to lay beside me, although occassionally she would get that hankering for face sitting, but would settle for sharing my pillow. just keep a water bottle next to your bed and when he howls at the door or whines or sits on your chest squirt him and say firmly NO. they get the idea quick enough.
