Do you accidentally have experience or do you know someone who has to work in these companies?

I’ve been thinking for a while now to quit the current company because I’m exhausted. The job as a job is great. It is not arduous physically, while psychic is from time to time. Working hours are desperate. From 06:00 to 00:00 in two shifts. The first from 6h to 3pm and the second from 3pm to 00h. Don’t ask me what it feels like to finish the second shift and the next day to be the first … He is solidly paid and I am really pleased with the income. But after a full two years spent at the company I just can’t anymore. I sleep poorly, eat badly and have no time to devote myself to myself, let alone other obligations in life. The first year was great and I couldn’t complain, while in the second year it was getting harder and harder for me. I have the feeling that I am "prayer" and that I will feel the same even after the vacation. I looked at a couple of job ads and the two got my eye on my eye. Any information is welcome, working hours, days off, shifts, income, relationship in the company … I’m interested in everything.
