No scam. It's pure fact. From the moment that the sucralose hit my stomach, yeast began to die. It tried to retreat to my sinus. I made a sucralose sinus spray and the yeast travelled back to my stomach and convulsed and died. Now, only a small amount of yeast live in the muscles of my upper back. Hot weather, inhaling hydrogen peroxide, exercise, and sucralose will kill it too.
