Why can't i sleep!?

i am always tired when 11:30 rolls around but i other seem to stay up till resembling 4 in the am anyone else enjoy this problem you probably just built up a desperate habit over an amount of time
i have that problem too and i fixed it using a few methods
1. lights out at 11 pm no matter what
2. return with up at 7, no snooze
3. no napping
4. relaxing and trying to clear my head formerly i sleep
5. turn off adjectives music, lights, radio
6. try to get rid of anything that will distract you
7. dont unseal your eyes
usually id be thinking almost stuff and i realized that it distracted me from sleeping
bar that i just have a sneaking suspicion that if u relax and not think just about anything you should be fine
if its serious, i suggest you see a doctor
too much caffeine or i think because its this Y/A that disturb you from sleeping. i know its addicting
