I think I know exactly what you mean.

Although, my sleep issues are derived from the coffee bean. I typically drink a couple of cups after work ( I know I shouldn't.. but it's SOOOO good lol)

As a result, I'm awake at 3 in the a.m and have to be to work by 10.

Have you tried any sleep aids? Listening to calming music?

If this is an issue for you that keeps rolling around, I would suggest talking with your doctor and following up on his/her recommendations.
