You must read a book called The Yeast Connection. I've gone the same route as you-had lifelong sinus problem, dizziness, two serious labrynthitis attacks, the MRIs, etc., with DRs. telling me to just live with it. The book, Sinus Survival by R.S. Ivker, is also excellent. The whole yeast thing makes a lot of sense and making the diet changes, etc. made a huge difference for me.
