I think more harm is done when trying to force a person into a certain body clock mode that perhaps their brain isn't naturally wired for. I was never a day shift guy. I tried midnight shifts...terrible! Finally I found that my body clock prefers the afternoon shift. 3PM to 11PM. I then stay up all night and fall asleep naturally at 6 or 8 AM. Try finding what sleep cycle YOU prefer and see if you can adapt your life around it.

Some peoples clocks just aren't geared to the 'up in the morning' routine. Trying to force that schedule often causes more problems than it can fix. If you can get what you need done using your own natural cycle then do that. Not all folks can do this because of lifestyle commitments/responsibilities etc that can't be changed or accommodated but if you can, it may provide the relief you're looking for.
