This would be incredible.

The closest thing now is amphetamine but it turns people into maniacs - presumably the action here is not actually the brain cleaning function of sleep, rather just preventing reuptake of neurotransmitting chemicals that would cause it, if allowed.

Would be nice to truly provide the mechanism in a synthetic form - I wonder what it would feel like to have the brain “slept” while awake.

Sounds like the plot to a horror movie.

This will likely turn them into a different flavour of maniac.

Just go to bed.
