Was going to suggest the same thing. A great way to break the cycle is to somehow wake up early one day and force yourself to not sleep. You'll feel very sleepy early in the night and will fall asleep.
I envy those for whom this is the case. For me, I might be dead tired during the day, but I will spontaneously regain energy in the evening - enough to delay my bedtime a couple hours again.
It's absurd and somewhat dangerous - if I ever pull an all-nighter on something, it's really important I force myself to go to sleep early the next day, because I will suddenly become full of energy again come 21:00 - 23:00, go to sleep late again, and suffer further come next morning.
