I don't have anything on working overnights, but I have sympathy for you. I'm going through a different change, transition from working in an office to working from home. Same job, just company forcing its employees to work from home to save money on real estate expenses. Sucks because my day and my daughter's is structured around me working from that office. Instead of eliminating my commute, it is actually going to double my commute to take her to daycare in the morning, drive all the way back home to work, then back up there to pick her up and get back home for supper. 120 miles a day all together. It's nuts, but there isn't anything for daycare in the rural area where I live, so she always commuted with me to a daycare near my office. She can't stay home with me - I wouldn't get any work done and she'd be bored out of her mind sitting here at home. She loves her daycare (with pre-k program), so taking her out is really not an option.
My family thinks I ought to start looking for a different job, but this is one of the few really good paying jobs in the area without having a medical degree, so I'm reluctant to start job hunting until I at least give this a good try. I've got 10 years in with the company. I'm giving it at least 6 months before I make a decision about whether I want to keep this job or look for something else.
My advice would be to give it your very best try for a period like 6 months and then evaluate how you feel about it, how it is working (or not) for your family, and then decide if it's worth it or not.
