How to break a hyperfixation and get some sleep?

Agreed with the comment about sleep music. Sometimes it helps me to something to get the days thoughts off my mind. Like I’ll watch a nature show or a movie that I’ve already seen before (so I don’t keep watching so I can find out what happens next). After I do that it is easier for me to transition to sleeping. Also, if I lay down and I just want sleep sometimes moving to a different place to sleep like the couch or floor kind of resets things and helps me sleep. I also takes sleep meds which helps a lot. Doing something relaxing like taking a bath helps as well. They make epson salt with melatonin it it which is so relaxing.
