I've tried almost every method I've read about and gotten all but a few to work. Lately though I discovered one of my own. I just let my mind wander normally until I realize that I'm dozing off, then I just keep repeating "I'm dreaming, I'm dreaming, I'm dreaming..." until I end up in a WILD. It probably only takes a few minutes.

To me its very simple and much less boring than laying there trying to count or visualize etc. I also find I am less susceptible to distractions such as getting an itch or my bf snoring when I let myself half fall asleep this way. Also, it can easily be done without WBTB.

I think there is no one "Most effective" method for everyone though. From reading these boards the past few months I've noticed that almost all of the successful LDers have a different method that works best for them. My advice would be to try multiple things and eventually you'll fine tune a method that works well for you.
