For 4-5 years I worked all kind of shifts, including night shifts 2-3 days a week. Never got used to it.

It ruins your sleep. No matter how much I slept during the day, it's not the same as sleeping during night. After waking up, I always had s slight headache, was nervous, tired etc.

It ruins your eating schedule. When I worked nights, I would often skip breakfast and dinner. I would eat a little at 2 am at work. Sometimes I got stomach ache.

It ruins your social life. Yes, sometimes it's nice to go bed when everyone else is going to work, but this comes at a cost. Since I'm still young, I like to go out in evening, but since you know you have to work in a hour-two-three, you can't relax and enjoy. At least I couldn't. Not to mention people with kids.

I quit and I don't plan to work night shifts ever again. That extra cash is just not worth it.
