I'm not sure about your thing of thinking that you must get some sleep whilst actually being asleep but have you tried an online course called Sleepio? I did and no longer consider bed-time a nuisance. I may have been lucky but I opted out after just five weeks but you can stay in touch with them as long as it takes. You'll be asked to keep a sleep diary and then log in weekly for the next session. You'll be guided along by a cartoon professor in whom, I for one, developed a liking which meant that I happily went along with his suggestions which, by around week 3, got a little more tricky because it centred on bed-time restriction. At the time, this felt a little counter-intuitive but it turned out to be the crux of the matter in my case. Turned out I was going to bed too early and staying in bed too long! Weird? Try it, my friend. it is absolutely free!
