Is it nap time yet?

Holidays have a terrible effect on me. It doesn't matter how much I sleep, I still want to have a nap. It usually starts about an hour after I get up in the morning and lasts for the rest of the day. Even actually having a nap doesn't help, as soon as I am on my feet again I want to go back to bed. Le sigh. And I have to go back to work next week........
