hi, I wanted to come on here and say that I had painful, stabbing in my toes at night, flashes of light on the outside edges of both eyes after dark, headaches and blurred vision. Went on for years. I had eye exams but the doctors didn't notice anything and I didn't tell anyone about the other symptoms.
I read about my symptoms, stopped using saccharin and all symptoms vanished. Absolutely amazing. I had been using the brand Superose in my coffee each morning.
