Everyone is different Sanctuary, but not having diarrhea is a good thing. You could probably force the issue and find a dosage at which you did get diarrhea and/or nausea, but it's not necessary and why would you want to, right?
Some people do not feel anything at all from the Miracle-Mineral-Supplement , and they want to get to the point where they are getting detox so they know it is doing something.
Taking probiotics is not a bad idea, although the more uncooked food we eat, the more beneficial flora we get from that too.
