To expand on “sleep is optional” bit earlier, in all seriousness, sleeping in the usual sense (sleeping in a bed, for example) is entirely optional.

Unless you have a rare disease, like “fatal familial insomnia“, your body will do what it needs to do (fall asleep, go into a short nap, etc.). There is absolutely no reason for you to go through the ritual where, perhaps because to a lazy person spending 4 to 5 hours unconscious is not enough of wasting of time, spend additional 10 to 30 minutes trying to make oneself fall unconscious for a few hours or so. If you had needed to be unconscious, you will fall unconscious.

Anything else is a luxury and should be recognized as thus.
