I've had some pretty fucked up sleep cycles lately, but in the opposite direction. In the space of about a week I went from going to sleep at 4AM to waking up at 4AM. It's a bit jarring. I think the first and most jarring change was triggered by travel across more than 8 time-zones. However, I have managed to induce something that seems similar through self-medication with caffeine and alcohol. Drink coffee/tea at regular intervals throughout the day. If you can manage it, have an early dinner with alcohol (for me, wine works best for some reason). I wasn't watching for it at the time, but I think I was still good to drive by the end of my drinks. The extra stress from using the caffeine and my withdrawal from it put me hard to sleep for nearly 10 hours.
The principle seems sound, but it's been untested and I hadn't had a drink of coffee for several weeks when it happened. The cafe-con I had managed to put me a bit on edge.
