I normally stay up anywhere from 1 AM to 3 AM nowdays during summer, but during school it's around 11 PM to 1 AM, leaning later more recently. I tend to wake up past 11 PM to even 2 PM at the worst, and the cycle keeps repeating of staying up ultralate. Sometimes I am woken up earlier, but I'm normally too tired to even try and just go back to sleep.
