Actually it was not Sugar infested yogurt...It was yogurt that was sweetened with nutrasweet. Supposedly that feeds candida too. BUt I got better. My die off was severe then too, but I got better. Took about a year on the diet. Actually maybe about 5-6months but I stayed on diet for 1 year out of fear which is th reason why I think I got better. You cannot go back to eating normally as soon as you feel better.
