Up until about waist I slept with it loose; now I sleep in a bonnet - I make a loose very high nautilus without any pins, put on the bonnet, and then shake it out so it’s free inside (I can’t get my hair in otherwise!). It’s made my morning tangles nonexistent!

I don’t remember who said that an unexpected perk of sleeping with a bonnet is the bonus built in eyeshade option but I would 100% like to second that.
