I have forgotten how to sleep anymore. Idk if it's a good thing or a bad one. Either way, I get extra hours to code. xD

Enjoy all sorts of brain problems in a couple years.

Insomnia is not a joke.

Not good. Really not good. As @Cyanide said, that's no joke.
Eventually you will collapse.

@Jilano tbh you won’t feel long term effects of lack of sleep until late 20s(in my case-even then you will have those effects but smaller effects are easy to miss) but then... it is not pleasant to realize you forget easiest things...

I wasted some good night sleeps to coding in my youth but much more to video gaming. It is ok to occasionally(once or twice in a month) lose sleep to coding but not worth doing more. I hate the “charisma” of sleep lacking caffeine addicted software developer...

Bad thing. Eventually your brain will be so foggy you’ll struggle with the simplest things in programming or even elsewhere.

It's bad. Get some sleep.
