Hello~I can certainly understand your problem, I am sensitive to all kinds of additives, it is not fun.
I use a terrific sweetener that has no side effects at all and is pure and great for diabetics and anyone wanting to watch their sugar intake; it is called "Xylitol" and it is found the fibers of many fruits and vegetables, including various berries, corn husks, oats, and mushrooms. It can be extracted from corn fiber, birch, raspberries, plums, and corn.
