Have you guys used modafinil to stay focus for long hours be it coding or studying. I worked 15 hours none stop

I don't know whether it's correct but i am gonna just put it out there

So long story short i am coding for 10 years now , and it came to a point where it's boring now so boring that even the most beautiful written code does not produce the same effect of achievement, and i started making a lot of fucked up mistakes, coding makes me sleep now
I came across some pills called called "cognitive enhancers" modafinil and adrell, does these really help?

Modafinil what what?!

Ok so one of the guys at work is banging on about nootropics and coding to get into the zone..... Dafuq is he taking that for?
And I thought a cheeky trip was enough to envision the program and become one with the code...... Not that I know.

Modafinil for programming? Any thoughts?
