Pain/Hurt
Im not back to work yet but i sometimes worked overnight when the person scheduled called in sick and i would always feel sick the next day/ Its b.c you changed your pattern and your body is confused and tired....i tried taking an overnite pos once where i worked from11pm-9am thurs fri and sat and it just did not work no matter how much i tried to get into a new pattern i would only get a total of about 5 hours of sleep for the whole three days..
