I have fibro/chronic fatigue for a few years now and finally learned about cortef/Isocort. I take Adrenal Rebuilder by Dr Wilson also.
As I detox ( parasite cleanse/liver cleanse/coffee enemas) I am thankful for the adrenal support. I could not do the detoxes without it. As a matter of fact, the parasite cleansing I believe has set me back some right now.
