"The feast of Less" and "The Candida Three: do you understand your battle with Candida?" were the most useful reads, but all have helped me. I've made my own herb mixtures and tinctures and it is the most powerful medicine I have ever used.
As for the "necrotic tonsils", I had the same thing as well. My left tonsil is wrecked because of this -- it looks different than the right one as it's now got holes in it. Food particles get caught in these holes and produce a foul smell after a while so I have to make sure I keep them clean. Since beginning cleansing and using immune boosters, I haven't had so much as a sore throat.
As for the obvious (refined sugar, alcohol, etc), stay away from it but do not give up on fruit. I had terrible candida and it was fruit that helped me in the end. All fruit contains natural beneficial bacteria. Yes, it will feed the candida but it will feed YOUR body quicker and make your immune system strong enough to fight the candida. Anyway, it's all covered in the link above.
Please read the information at the link and begin to make your own formulations: it's cheaper and WAY more effective.
