I used to use earplugs. Now I use an earbud and listen to books (nope, no timer..all night). If I roll over, I have to switch ears. Sometimes, it’s the same book I’ve listened to a thousand times over because my brain knows what’s coming and it’s hypnotic. The point is to stop thinking and just listen..get carried away in something semi-interesting. Turn it down so it’s just loud enough to hear over the voices in your head… ;)
