I've read that as time went by that it was discovered that taking small amounts of MMS over a long period of time worked better then taking large does less frequently.
I also see that protocol 1000 is to take MMS everyday for at least 3 weeks but I've never read an explanation as to why this is better (to take small amounts of MMS through out the day) and why for so long.
However I do believe the answers are hinted at when you read up and look at the videos regarding Autism. In those a lot of the talk is about using MMS to get rid of parasites such as worms, etc and that a lot of health problems we face might be caused by parasites.
I believe the answer to the 3 week question might be that Parasites have a life cycle and if you take MMS over a 3 week period then you can help kill the parasites at different stages of their life cycle process.
Doing an image search on life cycles of parasites brings up hundreds of images that help describe the cycle.
I think the parasitic information needs to rise to the top more. A lot of it is buried deep within the talks about kids with autism but very little is said about how parasites might be affecting all our healths without us even knowing we have them.
