my graveyard shift

I'm on my graveyard shift and thats from 11pm till 7am. It's not a busy shift but it's tiring coz i can't sleep comfortably on a chair and with the lights on. It seems that my body is screaming for a soft bed. hehe. When my shift ends, it's as if my body is floating in thin air and i couldn't wait to get home as fast as i can so i would be able to lie down in my bed and sleep. No matter how may hours i sleep in a day, my body is still weak and tired and when it's time for my shift i still get very sleepy. For two weeks i'll be on this shift and i just can't wait till it's over.
