You could listen to lectures from my high school biology teacher. That put me to sleep real fast.

But in seriousness, have you tried to limit stimulants as the day progresses? Like stop drinking coffee, tea or sodas after lunch? Ia there anything you can do that will help relax you before bed? Maybe a hot shower or bath, reading a book or listening to some music.

For a little while I was listening to Japanese relaxation music before bed. It did help me. I didn't find myself thinking as much and I just sort of listened to the music and mellowed out.

I haven't been sleeping well myself. Every few days I take some sleep meds to get a good nights sleep. My doc gave me trazodone. It is a antidepressant per its label, but isn't a strong one. It has a really common side effect of causing droziness. About a half hour after I take it I feel really tired. There is some carryover the next day sometimes. I have woken up a few times feeling drowsy.

They sell some sleepy time teas. I never tried them but I remember seeing them in the grocery store.

I find too much darkness makes it hard for me to sleep. Anxiety a little. My wife got a spinning glitter lamp for a birthday. It is usually on when I got to sleep. I think it gives my head something to concentrate on. It shifts between red, blue and green. I find it relaxing.

I hope you can find something to calm your mind down so you can get some sleep.

Lack of sleep usually worsens my depression. Too little sleep and I sort of go numb and feel like a zombie I guess.
