Lobby44, I don't recall if you are using 50% citric acid or 4% HCL to activate MMS for ingestion. If you are using citric acid, then change to 4% HCL and see if that helps with nausea.
Both CDH and CDS should be easier on your stomach is what we have heard from users. CDS may be best as far as stomach issues are concerned.
As to which SCS (sodium chlorite solution) might be the "best", Jim favors MMS1. It has been used for the longest time, so we have more experience using it than CDH or CDS. Keep in mind that all three of these SCS are made from the same two ingredients; MMS and an acid activator, and all produce chlorine dioxide (CLO2).
To use CDH and CDS with G2C protocols, you will need to reference
these
two chart to know the equivalent dosing to MMS1, which will be in milliliters instead of drops.
