Reason for activating MMS before drinking

I'm new to Miracle-Mineral-Supplement so this may be a dumb question.

Why wouldn't you drink the Miracle-Mineral-Supplement first, then the acid water and let it activate in your stomach? The bleach smell/taste is truly horrible and it seems the more I drink the worse it gets! Also, why wouldn't the hydrochloric acid in your stomach activate it just as well?

On a side not to those that brush with activated Miracle-Mineral-Supplement , does this stain your dental composite work? It stains the bottom of a plastic cup yellow.

Thanks, and sorry if these questions have been covered, but I couldn't find it in a search.
