i am not big on homeopathy(not opposed to it either), but there are some great suggestions here. i would like to add a hearty amen to fasting, but it sounds like youre not quite there yet. i know how scarey those symptoms are. do you have mercury fillings? i have to ask because you didnt say.
other than that, i had really good response to concentrace, the ionic minerals from liquimins and also oxygen therapy - all kinds. a magnesium peroxide Colon Cleanse along with drinking a drop of h2o2 in your water might jump start you. the h2o2 kicked my brain fog in the butt, i tell you.
