Been taking Lugol's Iodine, And using this relaxing audio by Jose Silva.
From waking up 4 or 5 times a night to being in a deep sleep all night.

Which one is responsible? Don't have a clue.
I am pretty new to Iodine. There are forums that would be able to answer your questions better.
Two individuals would be "Trapper", and "Grizz" on trappers forum who seem to be pretty knowledgable on the subject.
I wouldn't discount the Jose silva mind exercises. Here's a video explaining how it works.

Sorry, One verticle drop of 5% Lugols in about 6oz of distilled water.
The first Silva link I gave you wasn't about breathing, although it is important.
The point is that the human body is a universe unto itself, not just flesh. The whole, body and mind has to be nourished to get optimum health. The second link I gave you explains why.
