I don't think any of that is particularly good advice. The best way to adjust is to stay up an hour later every day until you reach your goal. (So if you go to bed at 6am, take two weeks to adjust that to 8pm.)

This avoids any sleepiness during the process, except maybe for that last hour. I did this successfully late last year, but ruined it by volunteering to help out at an overnight hackathon somewhere in the middle. Oh well.

Seriously? So to start waking up at 6 instead of 9, you should take a 3 week vacation and turn your schedule entirely upside down? Sounds a lot more disruptive than just sleeping/waking 15 minutes earlier each day for a while.
