> being sleep deprived for months does not make you bipolar maybe, but depression can and does happen
It shaves off 10 to 20 IQ points in me when I'm on a bad streak. I have failed FAANG interviews because of bad sleep. I still probably would've failed them, but it'd have been much closer. I literally remember one coding interview where I was thinking "if I just had enough sleep, I'd have a solid shot" (the other coding interview was so easy I could even do it in my half-ragged sleep-deprived state).
It's funny you should talk about sleep deprivation messing with your mind... I once remember trying to program a for-loop in C# about 8 or 9 years ago (I've been programming since the 90s) when my son was a baby. He'd been up and down for a couple of days as he was unwell and my sleep-addled brain wouldn't let me create a for-loop.
No matter what I tried I could not get the code to compile.
I still laugh about it now but it definitely highlights the importance of sleep.
