Yes, I too have difficulty sleeping but I've discovered it to be more cyclical in a pattern than sufacing motivation. In my case I believed it to be symptomatic of the epilepsy - my brain just would not shut down. Patternistic with 11- to 13-days in a row with sleeping difficulty, then 3-nights of "sleeping" ...but only four hours straight sleep, three hours awake, two hours straight sleep again.

My go-to approaches to motivate or entice the activity of sleeping are soft relaxing music, reading, and most often prayer. Meditating on visiting a place I could never ever afford is most effective, 30-40 minutes and 7 out of 10 times I drop off, but like I said sleeping comes in bursts. This has been going on for decades.

Whenever I dismiss epilepsy as boss cause of lacking motivation toward sleep, I consider that my body's functional needs do not demand the conventional eight hours every night, routinely.

Thank you for this post, very insightful question.
