I can't sleep!

I can't get comfortable and I can't sleep! I want to cry. I'm almost 38 weeks. Everyone keeps making the joke, "it's just your body preparing you for no sleep with the baby..." No, it's my body saying, "I've been carrying a boulder on my hips and it's a lot." I think they should give you the option to try out epidurals like a new car. Just a test run so you can sleep once before the baby comes. Numb me so I can knock out for a few hours! Please!
