I was hypoglycemic, but not diabetic using only exercize/ essiac tea /and proper diet. Had two bad episodes of low blood sugar..two days in a row ..the last two days of massage therapy school and my mind has been worse ever since . Low blood sugar & stress (like taking final tests) can really create problems. It took me at least 2 weeks to feel somewhat normal. Before that I thought only too high sugar would destoy cells. Thanks for the post. Aunt Bean
