@FryingMan: Based on what I've read, not just "more likely to get lucid", but also have very vivid and long LDs, thanks to the so-called REM rebound, due to sleep deprivation on the previous day. I've also read is really good to combine with another method like WILD.

I still have to say if it works for me... Requires lot of effort, that's true, but if it's worth it, I'm in. For example, right now is friday. Normally I would just have some beers, and stay up late until I'm tired (could be 11PM or 1AM, who knows), and wake up whenever I feel like it (11AM.... 2PM...). But currently it's 8PM my local time which means I'm off to bed in around 2.5 hours...
