well actually it works yes, i've tried it before. staying up all night long helps as well. does it make you a better lucid dreamer? nope, that comes with practise... but if you are stuck and want to *breakthrough* and have a LD that would be a recommended technique.

interestingly enough I was totally in sync with the first part, getting 3 hours sleep -- as a method for regular LD... but I would have suggested going back to sleep after an hour... i've recently found it works wonders for preserving lucidity the rest of the morning...
