Thank you. I buy braggs apple cider vinegar drinks, there's a cinnamon and a ginger one, from my local health food store. Since i asked you this question, i have begun to figure more out...i had already activated the mms with my 50% citric acid formula. Being new to MMS i noticed a slight foaming action, but the drink actually fizzes up a bit by itself. My lack of knowledge led to my question, so i'm pretty sure i understand what happened there. basically i added my activated mms to my vinegar drink and i got a little nervous not knowing if i was over-activating or not. I have two new questions. How long before or after an MMS dose should someone wait to consume carbonated beverages and vinegar/citrus beverages? Also, is it standard for the citric acid activator not be labeled what percent it is? i was confused when i first received mine and had to go back to the website (healthyliving.com) to see whether i had purchased 28 or 50 percent. I bought MMS mostly because i felt a strong urge to and knew absolutely nothing about it. As i am on my 5th day of protocol 1000 along with a sick friend who is getting results beyond our wildest dreams ALREADY...i am so glad i followed the instinct to do so.
