are you getting the original Masters II formula or the MLM version? The MLM version has been compromised, it is no longer the real formula. The creep who got permission to manufacture it from the originator decided to cut corners and increase profits. The originator has asked him to stop selling it with the same name and he has not complied.
Even if it IS the real McCoy, it sounds like your stomach acids are low (MM will neutralize stomach acids, which is why you're not supposed to take it with meals) and your electrolytes are low, especially calcium and magnesium (palpitations). OR you may have been infected with parasites, yikes. When there are a lot of toxins in the bowel or a compromised thyroid wonky things happen when we have a BM, even to the point of passing out. Lots of us have noticed things like dizzyness, palpitations, even arrhythmia. Very annoying to be sure!
So analyze your diet for nutritional deficiencies, and digestion for other symptoms that could lead to a more definitive diagnosis, read up on increasing digestive power, and see about taking digestive enzymes, Lemon Juice before meals, peppermint tea, 500 mg. of Vit C - all things that increase stomach acids.
Then read up on liver and lymph cleansing. When those are clean your face doesn't get so compromised with toxic overload.
Take the thyroid test - before even getting out of bed, take your temperature for an entire week. Note the results and average them. If the ave temp is less than say, 96.5, get a physical done that includes a TSH test.
Also analyze your diet to see if you're getting enough Vitamin A and Zinc. Cod liver oil is a fantastic source of Vit A. Nuts, grains and dark green leafy veggies have zinc. Just Google the phrase "foods high in zinc" and you'll get a good list.
Hope that helps! :)
