Going to sleep earlier and sleeping more hours is one of the easiest fixes for many, many troubles - more that you can imagine. I sincerely recommend the book called Lights Out.
@Steve Freides I need to be more strict about not bringing my IPad to bed with me. I often have trouble sleeping, even when running on 4-5 hours of sleep. When changing from overnight shift to day shift, and vice versa, I have trouble adapting, and must resort to sleep aids like over the counter sleep medications and low dose melatonin.
I could not agree more to go to bed earlier. Which I generally do, but falling asleep earlier is more difficult for me. Working shift work has really been changing my sleep habits. I do catch up on sleep when I can, but I have developed far from healthy sleep habits.
