My experience and learning from it. As to digestive enzymes, they are very necessary. Take them between meals, too, to help digest the garbage in the body. Some good strong ones are from http://www.docsprefer.com. If you have candida bad, don't use the ones with cellulase and hemicellulase.
I didn't go on any special diet. Doc doesn't have any diets he recommends. He says "eat what makes you stronger and what helps you sleep well". Review what he says in his book on his website.
