I am on a 5 day coarse of de- assidation with magnesium peroxide what are the normal sideeffects.?

See below. There is no normal for this completly bogus treatment. It may even be potentially toxic depending upon dose. All peroxides are very potent oxidizing agents and are not for ingestion. There is no such thing as being too acid in a walking talking individual and you do not need to be de-acidified. Save your money and your health.
