Pretty much everyone in professional services for major corporations fits this bill. Working for the big 4 and getting 5 hours of sleep is pretty much impossible. Adderall is essentially a requirement for everyone. Cocaine and Xanax for the more adventurous. That's not even getting into the actual finance companies and investment banks etc.

Same for emergency services in any major city or manufacturing facility. 24 on 48 off pretty much guarantees an all-nighter every 3 days. Then you can't really go to sleep when you get off at 7AM the next morning, because you need to get a good nights sleep on the second night because your next shift starts at 7AM.

I don't know how that works for your brain, but after the first couple months you just seem to adapt and your not tired all the time like you were in the beginning.
