I am an RN and work nights, 7p to 7a. I try to keep my schedule to 3 consecutive days soo that I can have a stretch of time off. I kept telling myself that I would adjust to to schedule. It has been almost 2 years now and I am still struggling. I am very non functional. I find it almost impossible to stay awake for longer than 3-4 hour increments. And do only those things that are absolutely necessary....like taking and picking kids up from school and/or their functions and often fail at that as well. We probably hold the school record for tardiness. Even worse is when I sleep through picking them up. I set multiple alarms, have friends call to wake me, to no avail. I sleep through it all. For the past year, we have been treating it as depression and ADD but the more I see articles related to shift sleep disorder, I wonder if that's not more of the problem. Any info would be greatly appreciated.
