Ok this is not to encourage anyone. Their is a pill , a stimulant approved by the U.S. Air force and the FDA, all U.S. Railroads and their UNIONS that is given to keep pilots awake for certain flight missions as well as railroad engineers. If taken right, you can be awake and suffer no ill effects for up to 40 hrs without sleep and minimal degradation of your abilities and sences. You will not "crash" and sleep for days after its use and you will function totally normal.
Modafinil / Provigil
It is VERY EXPENSIVE and only available in the U.S. only from a doctor, you can buy it online, and there is also a generic, it also works. Yea there are some side affects in some people, puking, a skin rash, nothing terrible. Them last time I bought it was a few yrs ago, I haven't used it since and if i remember I had to buy 100 , 100 milg, pills at a time and they ran around $8 a pill.
Again, I am NOT telling you to run out and get it and use it, the DOT might not take well to it, but with its use by the U.S. military and the Railroads, I'd bet you could win in court. All I can tell you is that IT WORKS......From there, it is up to you...
