I relate hard to this. While I still do it on occasion, it burned me enough times that I’m basically too traumatized to do it anymore. Too many rough days where I fuck up everything due to exhaustion.
One strategy has been rewarding myself for waking up early with a nice pastry or preferred caffeinated beverage on the way to work. Or just the small contentment of reading casually before I go in, instead of rushing until I run out the door.
Basically, if my mornings suck, then I’m going to stay up to “procrastinate” the morning, illogical as that is. So the strategy is to make the mornings (more) pleasant.
Another thing is no eating within 3 hours before bedtime. I find that digestion keeps me up longer and disrupts my sleep if I do doze off. The empty stomach in the morning also wakes me up consistently, like a built-in timer. If I’m up past midnight, I will be starving and night-eat which compounds the whole problem.
More than once (if that) per night is not normal. You should see a doctor if you have the means.
