Going earlier for bed does wonders for me as well.

That helps a lot with recall... and it is cool to take up and 2 am... realize you have already 2-3 dreams for the night, and still 4-5 more hours of sleep, which adds excitement and the posibility of a LD.

My most epic night, I recalled a wooping amount of 17 dreams... no kidding. Including 2 DEILDs and 3 L-DEILD (my own personal technique... which is chaining lucids - Lucid-Dream Exit Induced Lucid Dream)
