Sleep? I Hear It's Over Rated

It is 4am and I have been lying in bed for over 4 hours trying to fall asleep. To late to take anything but I think I need to find those sleeping pills the doctor prescribed last summer. The cats been in my face all night so I finally got up to find out that he was out of dry cat food. That explains his behavior. As for me, I just can't seem to shut off my mind.....
