Hmm, in that case i dont fully understand. He mentions sipping it and adding the fructose in the "method 2" suggestion in the link i provided (This comes under "Overcoming the Taste of MMS"), but nothing about sipping it in method 1. It appears that the purpose of the extra citric acid in this instance would be to disguise the taste (see 2nd bold print below)
"Overcoming the Taste of MMS
Written by Jim Humble
Follow one of the suggestions below:
Method 1: Mix your dose of MMS in any strength that you happen to be using at the time and use one of the juices listed below. You should be using 1/3 to 1/2 glass of juice. In addition to that, you should add two to three teaspoons of citric acid solution to the juice before adding to the MMS. If you find that these juices are a little strong for your stomach, just be sure to drink a glass of water or even two glasses of water immediately following the ingestion of the MMS and juice. See the paragraph below for the exact sequence.
So let me cover that one more time so you have the exact sequence. Mix your MMS with 5X lime, lemon, or citric acid as you normally would. Wait the 3 minutes as you normally would. Now before you add the juice to the MMS glass add two or three teaspoons of 10% citric acid solution to the juice and then ad it to the MMS. Drink that and then if your stomach is a little sensitive be sure to drink one or two glasses of water.
ABOUT BUYING THE JUICES: You can find Black Cherry concentrate by RW Knudsen that does not have added vitamin C. Pomegranate juice can often be found in health food stores, or frozen concentrates area in supermarkets or in very large supermarkets in the juice area. Cranberry juice is everywhere, except it is hard to find that does not have vitamin C added, but it is available. Buy it in the concentrate form if necessary. The addition of the citric acid eliminates the revulsion that many people develop to the MMS drink. Please try it as you will be needing it if you are one of those who cannot stand the taste. Good luck.
