Only try WILD if you can easily relax; it really isn’t an ideal first technique for most people, but if you are not distracted by typical problems like swallowing, feeling itches etc then go ahead.
Actually the solution to this is fairly simple - just let them happen, swallow if you feel you need to and scratch whatever itches you feel, and eventually you will be closer and closer to sleep and stop paying attention to them.
I personally started with the WBTB + MILD combination, seems to work brilliant when I actually take the time to try it.
In any case, you need to realize that the secret to lucid dreaming is chiefly two things - self-confidence and awareness.
You need to learn to be as aware as possible of your waking life (which basically means that you should try to notice more details with all your senses whenever you are awake: ask yourself if there are any signs of this being a dream, memorize how you got to a certain place and where you are going, listen to sounds in the distance, smell the air etc), and really believe in that you will succeed.
Not just “hoping” that you can do it, but really knowing that you will succeed in the future.
