All the music is very effective. I recommend you to try it. I hope I can help you.
Requiem, lullaby, serenade, string serenade in g major.

Just try it. It should work.
There is also a kind of people who think that insomnia is from the heart and should be worried.
Only by really starting from the heart can we solve it!
I hope you can have a good sleep ~
