My method is simple. Sleep little at night, say, 3-4 hours. Wake up at your regular time. (This will only work for people who can go back to sleep after 1-2 hours.) Upon waking, drink a large, stout coffee. Let it speed you up and go about your business for 1-2 hours. When the caffeine starts to drop you, prepare yourself for sleep and then do so. If you have a dreaming ritual, definitely use it before you sleep. There should be a certain fatigue noticed at this point, wherein going to sleep should prove quite simple and gratifying. It is this fatigue that should enable you to have an LD.

NOTE: EVERY time I have tried this method it has proved fruitful, which means that, according to me, it has a success rate of 100%. This may not work for everyone, but I'm willing to bet that it indeed may. Try it and see what you get. Best of luck!
