Does anyone have tips on how to stay asleep at night? I go to sleep fine but wake up about 3 am and can't go back to sleep. Would prefer not to have to take something.

W was very distant yesterday. We had to go pick up her car. It was getting fixed from when she hit a tree the other night. Really quiet trip, other than having to hear Erasure's 'A Little Respect' song over and over. She's been listening to it a lot lately. She forgot I always liked the song (sorry I had to admit that). She was humming it the other day and I asked her, is that Erasure? She looked puzzled and said are you the one that use to listen to that. She couldn't remember why she knew it. Her memory is shot,
