Christy, the protocol that you may still be using, that includes 1/8 tsp of baking soda, is no longer used because the baking soda neutralizes the MMS.
Some of the drinks mentioned here may not affect the MMS.
However, if you try the new way to make MMS called CDH and use 4% HCl for the activator, you won't need anything to hide the taste or smell because there really isn't any at the amount used in Protocol 1000.

When you start Protocol 2000 you will find that you can take more CDH than MMS because of the way CDH is activated. The moms with autistic children are finding that CDH is much more effective because the children can take so much more CDH than MMS without hitting the Herxheimer wall.
