I work overnights and have been having trouble too. When I get home in the morning I have just enough energy left to kiss my husband and son before passing out but am usually awake less than 5 hours later and can't sleep for the rest of the day. I can't sleep during the day before going in. Exhausted most of the time, just hoping it passes soon and I get better at sleeping because I've got a pretty huge level of responsibility at work.
