When you sleep irregular hours, your internal clock, known as circadian rhythm, gets altered and our body doesn't know when it's supposed to sleep. You should set an ideal time at night to sleep in a manner where you get 8 hours of sleep, so avoid trying to sleep in the time in between. You don't need any medications to wake up early.
