New, tried it 5 times today (long)

Hi, I have been reading about this, and got some sunflower oil, and did it 5 times today. It foamed up all five times. I was doing a lot of computer stuff, so it was sort of easy to fit in today.
I am guessing that I must be very toxic to have it foam white all five times? I didn't experience any earth shattering miracles, but my teeth seem whiter, and my face skin seems rather oily tonight... hope I'm not covered in pimples tomorrow.
I've been trying to make some changes to get healthier. Started ACV, I am taking orotates- calcium/lithium/magnisium/potassium at night with GABA/Taurine/melatonin for sleep/stress/anxiety, and a good multi vitamin, and have been slowly crawling out of a horrible depression. One thing I am taking that maybe has made it easier to do this is serrapeptase. Now there is a true, experience a miracle on the same day. I had bronchitis/asthma, and probably pneumonia (too sick to go in for the xray, and the dr ordered Antibiotics over the phone, and they didn't work, two rounds of it at that!) and in four hours, I stopped coughing after my first dose of serrapeptase. I'll check later if there is a discussion board on this stuff. Anyway, perhaps that is why I am not experiencing radical things, because the serrapeptase helped me so much already. Nevertheless, I do think there might be something to this oil pulling, and healing the entire body (I still have lots of stuff to heal, toxic, bad life style, overweight, smoker, etc) so I'm looking forward to see what happens here.
One question I have is what is this Iodine stuff? There is no page explaining what Iodine pulling is. Could it help with a sluggish thyroid? Could it help me to lose weight?
Thanks :)
