Fluconazole, please look at lee silsby enhansa protocol. Be carful of high dose anything and remember that strong herbs can give a burning sensation in the stomach so be carful. Some people advise probiotics but you could make his condition worse. I have read parents forums on the internet stating that they have such a brave child who cries when they have g.s.e. Because of stomach pain. They don't realise the harm they are doing.
