When I am not working the night shifts I go to bed about 11 pm and either don’t fall to sleep at all or think I sleep only 1 or 2 hours. I am tempted to lie in in the morning until 9 or 10 am hope that sleep will come but it never does. Occasionally after 4 or 5 days I may fall asleep unexpectedly for 3 to 4 hours. I try not to worry but its never too far away from my mind.
