I'm sorry to hear this. However, I'm glad that some people are willing to work these kind of hours to keep things moving. I understand that many people enjoy it. Especially reclusive type people.
My mother worked for 35 year in a textile mill on the 2nd shift. Something like 4PM until midnight or so. She had an hour commute; so, it was after 1AM before bedtime. When she retired, she was never able to adjust her sleeping habits. Since I did it for only 3 years, I had no problem and I was young then. Yes, I said young; not younger.
