Posted by roblynol on March 08, 2007 at 03:28:55:Is anyone aware of a type of sleep disorder that does not allow a person to sleep during the day. I have never been able to work night shifts due to the fact that my body will not allow me to sleep during the day no matter how tired I am. I am in a dilemma now because my current job is trying to force me to work the night shift so I am trying to provide an explanation to my situation. Any help is appreciated.
