Yes, I have read The Yeast Connection; I thought it was a good book.
I also struggle with weight loss on this diet. I know I will lose weight. I did a VERY strict diet in 2010 for 2 weeks, and it improved my symptoms right away (though I did have a die-off reaction as well).
Since then I haven't been able to maintain such a strict diet; it's VERY hard for me, from the weight perspective, always being hungry and just my on the go lifestyle. I eat out a lot.
