Sounds like you've got it rough. It is possible for shift workers to cope with irregular hours, but when your hours change it's very difficult. What would really help you is a regular sleep/wake time, every single day. You also have to have a dark, quiet place to sleep. No phones, no tv's, no noise or anything else to wake you. This works fine for someone who lives alone, but you have a family...so the ultimate solution would be to find another job, or atleast start looking. And your boss isn't going to work with you on it...so yes, my advice is to just take your time and find something else with better hours.
