Molybdenum is something you can try. Since brain fog can be associated with the symptoms of hangover, candida gives the same symptoms since its like something fermenting like your a brewery. I used this when I was in school and it seemed to help some. Even tho I dont have any candida issues at this time I still get foggy when I eat something like pancakes. I use to have the Denny's meat lovers plate in the morning at times. I seemed to always feel like I was drunk after, for a few hours. When I found out about this it semed to help. As far as the die off symptoms i wouldnt try to avoid them. This was the hurdle I made it over and seemed to be the only way to kill the candida. Twice I went thru this but only when I consumed probiotics afterwards for a few months was I able to stay healed. Been 14 months now and no allergies. Just brain fog at times from certain foods. Look this stuff up. It says that its effective against candida brain fog.
