Hmm, I've had some easy success using a different method. I'm not sure if it's actually a DILD, but it's not a WILD.

Well, you know how it is when you are waking up from a normal dream? You go, "ah, I should have realized I was dreaming," and for a moment you are still half into your dream. Right at that moment, right before you wake up, you have to concentrate really hard on NOT waking up and staying in your dream. If you can stay in your dream for another second, and get it a little more stable, you can start to stablilize normally (e.g. rubbing your hands together, spinning around, etc.). You are immediately lucid and you can retain that, although I'm not sure how long the dreams last.
