Query: A 600+ page advertisement for other books

I was extremely disappointed in this book! I bought it because it was the most up-to-date of the Crook books, and was hoping for serious, factual discussions and step-by-step instructions on how to deal with yeast related problems. Instead, I find hundreds of excerpts from letters to the doctor (nice, but tiresome after a while), and broad overviews on important topics with references to other books. Getting to the most (in my opinion) important topic - modifying your diet - there is ONE PARAGRAPH about the initial diet and something like 'in general, you want to eliminate all sugar, yeast, etc...' OK, but how about IN SPECIFIC? This problem was repeated throughout the book - just when you think you're going to get some valuable, specific information, it says 'as discussed in The Yeast Connection,' or 'as discussed in The Yeast Connection Handbook.' I don't want/need an ad for THOSE books, I would like the information in this one!
