I think the 1ppm in the first paragraph is what raised my eyebrows. I did not wade through the whole thing but it did make me at least consider there may potentially be some long term negative effects of long term exposure to mms. I will probably still try it if I am not feeling better by the time my mms comes in the mail. I will just go very slow and stay tuned in to my bodies responses to it. I know our bodies can get rid of lots of toxins if we don't overdo it. I notice that no one in the survey took 2 or less drops of mms each day. Is there no noticeable affect at that low dosage?
