To stop going to bed at two in the morning, I didn't sleep for two days (not consecutively), and then I started waking up with an alarm. The day before yesterday, I went to bed at 4 and woke up at 7. Today, I managed to fall asleep earlier (since I also started feeling tired earlier). I fell asleep at midnight and woke up at 7.
Also, long sleep is harmful.

I visited my profile once and ended up with such a round number.
By the way, Locken listened to a lot of things from here:cool:
