After not sleeping for a day so I could fix my sleep schedule, I went to bed early last night and ended up just sleeping almost sixteen hours and waking up at the exact same time as usual. So that was nothing but a big waste of time.
Sleeping is "hard to solve thing", it is a program for your body written hard and needs much time, what is different to everybody. For me, it's no matter if I go to sleep at 20:00 or 0:00, I will wake up at ~7:00.
