So Tired

I'm tired. Sleep issues. I can fall asleep but I can't stay asleep. I'm awake for a couple of hours in the middle of the night. It doesn't make me happy. I just want to sleep every single night all night long. Is that too much to ask? A week of solid sleep with no getting up to pee, letting the dog out, is that too much to ask for? Really, I don't want to be selfish but couldn't that just happen for me?
