I'd say it's a curse. Your case is very familiar though; I used to get maybe 4 hours of sleep a night when I was more of a night owl too. I think it's partially a societal problem. Some people are just built to stay up during the night. If you look at tribal society, someone has to be the night watchman, right? Not considered acceptable anymore.

I balanced out as I got older. Only 28 now, but for the past 2 years I haven't been able to keep myself awake past 12/1am. Hopefully it'll improve for you over time as well :)
