Thanks Emma for finding this thread. I knew there was one. I think we have talked about sleep issues is a lot of other threads but I'm glad you found this one and pointed it out.
Even better, just a couple of posts above is a decent summary of my Dos and Don't which I mentioned to
@Jools Holland.
As I have said before I don't have any trouble falling asleep. my main issue is staying asleep. When I'm awake at 3am, sometimes my brain gets busy with negative thoughts. so I've found that I can distract my self by listening to an audio book. My problem with audio books is that sometimes they keep my interest too well, or if I fall asleep before the sleep timer goes off it can be hard to find my place. So I think I'll try your suggestion.
I also have some apps that have guided meditation and other sleep aids. My HMO gives me a subscription to the app Calm.
Right now my favorite thing is to listen to an audio book of a book that I've already read before. It seems to work better for finding where I left off the night before.
The last two winters I've been sleeping so much better. I think it's temperature related. but could be something else too.
