Thread: The enemy: Swallowing.

You're over-complicating things.
Becoming lucid only means that you try to bring your critical awareness with you into the dreamstate, and WILD (which you seem to practice) is one way to do that.
It doesn't mean that you must lie absolutely still and play dead until you fall asleep, it only means that you should relax and allow yourself to fall asleep while still maintaining your awareness.
Trying to avoid swallowing is much more distracting than just swallowing and get it over with, and swallowing shouldn't ruin your attempts as long as you don't focus so much on it.
In fact, if you allow yourself to swallow in the beginning then you will eventually start doing it automatically after a few minutes, kind of like how you breathe automatically.
