I have always been of the mindset that doing any of the ML protocols different than instructed is not really doing the ML protocols. I do realize that some people have to learn to do the best that they can at times but if you have access to the correct ingredients, then I would do that.
Calcium carbonate does not have the same effect as the calcium hydroxide. (Added Note: 1 Tbs of calcium hydroxide must be added to a gallon of distilled water before use and shaken very well) If you are just getting started, I would not use any calcium at all because it has the strongest effect on people. Just stick with the epsom salts and H202 to the bath...see how you do with that first. Don't worry about fluoride at this time...step by step, you will take care of that problem too. Be patient.
Hey, a hot bath would feel good right about now...wouldn't it. lol
