You have not described any problems you might be having due to lack of sleep. You have only mentioned that you can't sleep at night, and that you are too busy to visit a doctor.
I would infer that you have a lot of work to be done. In that case, sleeping less might actually help.
So, please describe your problems if you want some answers. Lack of sleep is not a problem in itself. If I was given a God gift of staying fresh and energetic as ever without sleeping, I would never sleep!!!
Hope you got the point.
