Ok I thought about this: What about attaining Lucidity by eliminating everything that could possibly make you not have it? By going against all that can make you not have an ld.

E.g, To attain wet lips: stay out of the windy cold air (LOL bad example but anyway). Hang on, the correct word might be: sustain

I wonder if there's research on this, or maybe there already is... What do you think?
