It feels like shit tbh. I work at a Utilities company. I work 8 hour day shifts and 16 hour night shifts this repeats twice and I'm given 2 days off. Thankfully, it's all quiet at night so we can snooze a bit.
It can get hard working the morning shifts since I like sleeping late. Regardless, I'm always tired. I'm not physically tired like manual labor tired but more or mentally exhausted tired all the way. Do it for 4 years though and you get used to the feeling of being tired.
I do feel that my IQ has gone down from the constant lack of sleep.
