I remember when i worked in a warehouse. 5:30pm-3:30am, if there was alot of work there was a 2 hour clause in which we had to stay. so during the holiday's there was alot of 12-13 hour nights. I thought it was ok at the time, now that i have a regular 9-5, i dont know how i did it. everyone always says "but you get the whole day to yourself", no you dont, i slept as soon as I got home till 3-4pm, then off to work again. That shedule sucked, i dont mind 2nd shift AS much but now that ive worked a regular shift job i dont know how i did it. Even though im still a night owl and stay up till 1-2am most nights.
