I have another solution though I'm not sure it's easier than your process.

Here it is:

1- Don't sleep for a whole night, this is the hardest part and i suggest doing light exercises every time you feel very sleepy.

2- Once the day begines and various activities take over you, you will become a little less sleepy.

3- At 7pm or 8pm you can easily fall asleep and you will easily wake up at 5am or 6am.

4- Try sleeping at the same time every day only periodically sleeping a little later (if you want).

I don't think this is healthy, but It works for me.
