I just teased my hair really big, I'm tired and I don't want to ruin it in my sleep. Help?

Okay so around 2 I got bored and straightened and teased my hair. It's really big and took me a long time to do. I'm tired now, but I don't want to ruin it in my sleep, I toss and turn. Any tips? I really don't want to have to redo it.
