Well, when something makes you feel bad it could mean it's making you better. So...I'd clean up the Herxheimer reaction by killing off the bad guys more directly, and detoxifying the by-product of the yeast and dead bad guy cells that cause the most reaction. Take some Caprylic Acid to kill off the bad guys, and take Pantethine, the metabolized form of B-5, which is the only thing that detoxifies the tissue-eating waste by-product of Candida, Acetaldehyde. Then seed the good guys with home-made kraut, or consider trying something like Nature's Biotics. Choline feeds the sleep center of the brain so have a poached egg yolk or two for din-din.
