I Need Coffee Again

The quarter two was over in company calendar.Finally, it's transition time! Working in night shift has advantages but more disadvantages for me.The advantage is we have additional night shift premium and it is not much pressured than working in day shift.The top one disadvantage is my muscles pain or arthritis. I really suffer it because of chilly temperature all night.I need a coffee ! My body clock will change it's sleeping habit.I don't want to fall asleep on my duty or else I will be fired early.
