This may be in the wrong thread; sorry! If you haven't heard of this trick, it actually helps you fall asleep within a minute.. Here's how you do it:
(recommends learning it while sitting with your back straight.) Before you begin, place the tip of your tongue against the ridge of tissue just behind your upper front teeth, and keep it there through the entire exercise. Now, follow these steps:

1: Exhale completely through your mouth, making a whoosh sound.
2: Close your mouth and inhale quietly through your nose to a mental count of four.
3: Hold your breath for a count of seven.
4: Exhale completely through your mouth, making a whoosh sound to a count of eight.This is one breath. Now inhale again and repeat the cycle three more times for a total of four breaths.

Could this be used to maybe achieve WILD? I might try this over the weekend and see if it helps.
