It's hard as hell to get used to it....and in all honesty, my body never really gets used to it. The stretch where my rotation has the 5 days off is when we're preparing to switch that second week, so we can sort of start trying to sleep during the day is we're on nights or vise versa....it's still hard, but we only work 14 days a month, unless we're pulling overtime, which we were doing A LOT before I went on leave.....there were days I was going in at 5:45am and not leaving until 6pm the NEXT day....
