Ooh, I have an answer that works. Get really fucking drunk over the course of a couple of hours starting around 8pm. Then take a moderate sleeping pill. You might need to train for some years, first, to not wake up with a hangover.
Source: wake up between 530-630am naturally on weekends.
For anyone reading this - do not do this. There is a huge risk of aspirating on your own vomit and dying because you don't wake up due to the sleeping pill.
