T minus 10 minutes and counting

Set your phone's alarm for 5 minutes so that you tell your brain you can forget about CYL until the alarm alerts you.

I used to use a similar technique if I had too many thoughts or things I was trying to remember before going to sleep - just write them down, and next morning I can just look them up. Then my mind can stop exerting itself making sure I don't forget, and it's easier to rest.
