overnights-good or bad???

So, I was told I will be going overnights, but first I have to be replaced. I was hopung to start Sat., but we will see. I am excited for the extra money it will bring in and the availability it allows during the week for the kids. I will work Thurs-Sun 9 or 10pm to 6 or 7am. I have not done overnights before, but D. and the kids are going to very supportive and allow me to rest hopefully, or at least as much as i can get with 5 kids, 2 dogs and a husband. Soon, we will be in full swing into the holidays. Wal-mart already has Christmas music playing and FM100. I am very, very excited. I love Christmas, so my kids plug their ears in the car.
