Sleep Apnea Treatment

Okay, ever since summer started, I’ve been staying up late. Like, up until 1AM and stuff like that. I didn’t think about it that much, since it is summer vacation. But recently, it’s gotten worse. Most nights, I can’t go to sleep until 3 or 4AM and then I don’t wake up until 2PM. Some nights I just don’t go to sleep at all. And no matter how hard I try to go to sleep, I just can’t do it.
Is there anything I can do to fix this?
