My CFS is viral based. I have a whole bunch of herpesviruses in me that I fight to contain each day since I have had them. I find that taking BHT and then giving your body some time to detox aka clear out the havoc wrecked since day 1 is the best way to go. All protocols are supposed to last a lifetime. The only positive thing I can say about this is that after having lived with it for so long I am now more sensitive to the symptoms and can be more poractive instead of reactive towards it.
