The reason you are having throat discomfort is because CDS is fully activated externally whereas MMS1 is about 10% "activated" so contains much less CLO2 externally.
Two fixes would be to use more water with each dose and/or hold the dose in your mouth a while for some CLO2 absorption in your mouth before swallowing.
You could use
CDH
which is 50% activated externally. Use 4% HCL and not 50% citric acid activator for a much better taste. CDH has a two week shelf life if kept in a fridge.
By the way P1000 says a 3 drop dose of MMS1 is the maximum hourly dosage and is not necessarily the goal. Some people with stage 4 cancer have recovered their health using only 1/2 drop and 1 drop doses of MMS1. Something to think about!
Jim says reports from users claim better success with MMS1 when doses are made hourly. I measured CLO2 content of MMS1 hourly doses from an all-day bottle and there was no difference between the first dose and the last dose. Also measured the increase in CLO2 of the first and last doses in simulated stomach acid and again saw no difference.
You can use MMS1, CDS or CDH for protocols that produce CLO2. I presume you have seen the dosing chart
