I put on some headphones, fire up the tablet, and watch ASMR videos.

This link explains what they are:

My favorite ASMRtists are Gentle Whispering, Olivia's Kissper, and Visual Sounds 1.

Oh, and BTW, if you're going to take Tylenol PM to sleep, you might as well just take Benadryl or Unisom, as the PM part of Tylenol PM is the same stuff--just an antihistamine. There's no point in taking acetaminophen unless you are in pain, and taking it for too long is not good for your liver. Acetaminophen is not this benign, mild drug people in the U.S. tend to think it is. It's tightly regulated in the U.K. because it doesn't take much to be toxic.
