Years of reading in bed late at night while exhausted have conditioned me to associate reading with falling asleep. I don't have insomnia much anymore, often the opposite. Any time I want to lay down and read my book before bed, I'm out like a light before I finish a single chapter. It could be a super power, but it also means it takes me months to finish a novel. Also not ideal when I occasionally need to read reports or training materials at work and get to the end and my head is on the desk and I can't keep my eyes open.

I have a very stubborn brain that will usually do the opposite of what I want.

My method is to try and turn on a movie or something I really have to pay attention to. I'll start struggling to stay awake to keep track, and that will knock me out.
