I've never had a doctor tell me it was impossible, but two neurologists have told me I'm not diabetic or pre-diabetic (after repeated testing), and I definitely experience exacerbation of my symptoms if/when I indulge my sweet tooth. HF corn syrup is probably the worst, followed by sucrose (table/confectioners sugar). Artificial sweeteners don't cause the same problems, but they don't taste... "right."

It just seems so weird that I'm not a diabetic, but eat/live pretty much like one... (Curse you, Emperors of Chocolate! )
