I believe Trapper linked you to many wonderful testimonials. I lost my carpal tunnel syndrome by day two of OP, later on (within weeks) improved back, lost pains in feet and knees, no more pre menopausal symptoms OR premenstrual syndrome, thyroid has improved, weight loss , improved stamina for exercise. Oddly (and it took me awhile to realize this was linked to mercury poisoning) my eyebrows have gotten much thicker on the outer edges and filled in, and I read that one of the symptoms of mercury toxicity is thinning of outside eyebrows. So it is interesting that the oil pulling has helped with this as well (which explains the better thyroid function and weight loss aspects of things).
Also, I used to go to the chiropractor regularly, every 4-6 weeks, my last appt after three months with no visit had the doctor asking ME what I had been doing, he has been working on me for 5 years and had never seen my back doing so well with so little to adjust. I had only been oping for about 7 weeks at that time. I have not been back to him since.
I have also noticed certain oils had me losing some of these improvements, so I would check out different oils if I were you and not experiencing anything noticeable. Even differences in brand seem to make a difference.
It's true what I think North Coast man said, if you op and your diet is crap then you will not get as much of a benefit out of it. Your body will be too busy just trying to dump all the junk you are putting into it instead of being free to work on deeper issues.
