If it truly gets to where you are not able to get to work, or function properly when you get there, then you might want some med to help you. There are lots of drug that can help induce sleep.

I suffered for years, falling asleep at school . . . needing to lie down during my breaks at work. Staying awake for two days at a time. It was awful. Then I was put on an antidepressant that also helped me fall asleep. My life became so much easier.

Anyone with a bona fide sleep disorder deserves help. Also, try to always work a day job.
