I have not, yet. Sodium Chlorite seems to make better sense to me right now. both have risks I suppose. but for now I am more comfortable by the risks posed by Miracle-Mineral-Supplement . people forget that anything can be harmful if the dose is too high, even water. all the negative posts i have seen about mms, when you read the links, is either about the concentrated gas, the powder, or in very very high doses. as such, I see little cause for the alarmism.
