Having trouble to fall asleep and sleeplessness is typically called insomnia, that it is paired with delayed sleep phase is an unfortunate side-effect for those days that I did get (some) sleep, and from my preference for working when it is quiet (ie: nights).
The one feeds into the other which eventually results in missing lots and lots of sleep. I was under the - mistaken - impression that you can get by on 4 hours of sleep or less but this is really not the case so if you suffer from this in some for or other then better take it serious.
Sticking to a routine, avoiding stressful subjects just before sleep, relaxing activities (music, reading) before trying to fall asleep all helped in making it easier to fall asleep. Staying asleep is another matter, and addressing the noise that reaches my bedroom is one more thing I plan on tackling to avoid frequently waking up during the night.
