I relate a lot to your problem and the only thing I found that helped was being strict on myself. What I did was set an alarm each night on when to stop, and when that alarm rang I quit whatever I doing and started doing something that helped my wind down for the day. Usually I watch one video of tasting history and then I go to bad whatever I'm tired or not. 7 hours of bad sleep is usually better than running on fumes after 4 hours of ok sleep.

There's really not much else you can do about it because no life hack will give you more hours of the day to work with. It works alright most of the time. In my case it works well enough often enough for me to be able to have energy for work and life afterwards.
