Jim Humble and Dennis Richards recently released a you tube video discussing a mishap that occurred while someone was following the Miracle-Mineral-Supplement protocol.
It seems that they poured a large dose of Miracle-Mineral-Supplement and then drank it down. They ended up in the hospital with kidney failure. The excellent care of the hospital staff was able to keep this person from dieing, but I believe they are still in recovery.
Not sure why this happened but there seemed to be some confusion about the protocol preparation.
