I'm right there with you on not feeling like I'm done with the day. After my son goes to sleep I a precious few hours to myself, of which chores takes a fair chunk - so I might have only one hour of "me time" if I go to bed when I should. So often, that 1 hour is pushed out a wee bit. Brain works much better on at least 7 hours though, but that time at the end of the night is really my sweet spot and I savour it like nothing else.
At any rate, I find reading using the Kindle app on my OLED device (S8+ or S2 tab) with bluelight filter enabled (native filter on S8, app on S2 tab) with lowest brightness (white text/black background) to be great.
I'll start off with a bit of sci-fi, and if it gets too exciting I'll then switch to something less exciting - e.g. continue my work on the blue book (DDD) or something like that. ;)
Lifting weights in the gym also helps (e.g. 5x5 stronglifts), and not just for sleep either.
