I tried doing this in college too but it broke down immediately. The way coursework and exams are conducted almost forces you to burn the midnight oil and sacrifice sleep for forcing another three or four things to memorize into your head.

That’s what it felt like, like I had very limited time to shove x amount of things into my brain which only processes at y rate, so if I had too many things to shove in at a time due to taking a full courseload, that meant staying up since I cant change the rate my brain digests information without abusing stimulants like some of my friends.

So then you end up with a few nights of 5 hour sleep which you pay for by sleeping for 13 hours on the weekend. Not healthy, but it became a matter of necessity due to also having to make time for a part time job.
