This may seem a strange thing, but if you give it a chance, if you are susceptible to to ASMR or Asynchronous Meridian Response, there is a strong chance that these videos will KNOCK you out I've been using them for nearly twelve years and I cannot sleep without them.

Go to youtube and type ASMR Their is a MASSIVE community of extremely friendly individuals who all make "Relaxation Videos" They may seem a bit weird at first, but I'm telling you, they can be a godsend for going to sleep.

ASMR has strong ties to Hypnosis, and can help Lull your brain to sleep, Help ease the mania.

A few good videos to "ease" into the ASMR experience re any of the videos made the "Queen of ASMR" GentleWhispering

I'm new so it won't let post a link
Again, call me a weirdo if you like, But I sleep EVERY night now

Good Luck!
