My DH doesn't do an uneven time roster and we still are very flat the day before and on fly out day. The FIFO groups I'm a part of, most people feel the same way. I generally have to have something to look forward too such as my trashy TV shows at bedtime or have a planned outing on the weekend. It's also really hard after a big break! DH usually has 6 weeks off over Xmas and the holidays and when he goes back its really crud!
I hope you find a good routine. This is our 4th year and the lifestyle is starting to wear thin.
