I had CFS since 1996, very slow improvement. Then a breakthrough with the protocol of Dr. Myhill. Free book here: http://www.drmyhill.co.uk/wiki/CFS_-_CFS_Book_published_by_Dr_Sarah_Myhill In the last two years and this year again I had relapses in February/March. They scared me because I had been doing so well and I was afraid that the years of suffering would come back. I got out of them with the same procedure, but it took weeks. Just now I have found that the following product by Dr. Shallenberger worked literally micracles for me. I have basically recovered from my relapse within 2 days!!! http://www.advancedbionutritionals.com/Products/Dr.-Shallenberger-Favorites/Advanced-Adrenal-Factor-ABADRENAL3.htm I have been taking two times 6 tablets daily for the last two days of "Advanced Adrenal Factor". And I feel well! I was in terrible shape last Sunday and now I am fine. Quite incredible. Highly recommended to give it a try. (And no, I am not affilliated). I have also been adhering to the things most people recommend in the past years: - Good multivitamin - loads of B12 - Magnesium - Vitamin C - Special antioxidants (Res4 by Dr. Al Sears works great for me) - healthy diet - strength and HIIT training (within the limits I can tolerate, but pushing the envelope) - complete abstinence from any chemical drugs, psycho pills etc.
