Poll - How do you sleep?

I have heard a couple of times that some friends of mine have never been away from their spouse for more than a day. And these aren't recently married friends either, we are talking years of marriage. And I have also come to the conclusion that people who can say this are not married to doctors.

Anyway, my sleeping (or lack thereof) habits were on my mind. (Anyone else have a hard time sleeping alone??) You can select more than one answer.
