Night Shift

I have been looking forward to starting the weight loss cure. I have already started switching to organic as much as possible and have done cleanses. The problem I am seeing is that you are supposed to stop eating after 6pm. I work night shift, so I don't wake up, depending on when I go to bed, until between 2:30 and 4:00 pm and I get to work at 7:30 pm. How are you supposed to do this diet when you can only, forcing myself to eat, get one thing in to eat before 6 pm? I was already told by my late Dr. that eating once a day was very bad for me (which is what I am used to doing). Sorry, but I'm frustrated already and haven't even started the diet! Any helpful suggestions?
