Greetings, All. Quick background: I became very ill in 2008 after a bout of walking pneumonia and strep (caught from a passenger next to me on a plane). Eventually, both Rich Van Konynenburg and Garth Nicolson helped me get well. I discovered I have the homozygous C677T mutation and the protocol got me through and over the CFS. I stopped the protocol almost a year ago. I have been well....until recently. I have an old house (50s) with loose rockwool insulation laying on the attic floor. Early June I had central air conditioning installed in my home (I never liked A/C), and the musty smell of the rockwool started circulating in my living space. I became concerned and bought a large air purifier. It blew a black film on my closet door and walls within hours. The A/C return filter was black in 3 weeks. I began having sympoms of red eyes--which became worse and worse. I went to several doctors--"you have dry eyes." I became allergic to many things. The orbital area around my eyes swelled, and then my face swelled as if I was on steroids. I became foggy, unclear, forgetful and -- I would say--even depressed. My hair started falling out, my nails stopped growing, my skin became so pale that people commented on it. By the end of July I was right back into full blown CFS. It took time, but I had a contractor suck out the insulation and put environmentally sound insulation in the attic. I ran blood tests (myself) and found my blood count was mostly normal, but my B12 was sky high. I realized that I was having an enormous physical reaction to the toxins in the air, my B12 was just building up in my blood, and I was not using my B-vitamins that--in normal people--helps fight against stresses. I started back on the protocol and it did not seem to work until I took one complete FolaPro tablet. It was like magic--I had some strange brain-buzz sensations at night and could not sleep well--but I felt remarkably normal the next day. I'm writing this to make one point and ask one question IMPORTANT POINT: Environmental toxins are JUST as stressful as emotional and life stresses. Check your environment and especially these air-flow systems! I was very skeptical about such things, but now I see this is critical. QUESTION: I am not sure that the "simplified protocol" is absolute. It seems to me that a larger dose of the FolaPro was needed by me. And I am wondering if that FolaPro is using all the B12 in my blood--or do I need to continue taking the Perque B12? Thanks very much. Miss Rich Van Konynenburg very much--as I am sure you all do!!
