If you haven't discovered Stevia, go get some. Now. It's a natural sweetener that's derived from an herb from the sunflower family and has a negligible effect on blood sugar.
Get off of the sugar/starch roller coaster. You don't need 4 venti 3-shot vanilla latte's each day just to stay awake. Plan your meals so that you don't have an insulin spike followed by a "i need some toothpicks to keep my eyes open" crash.
Start reading your labels. Corn syrup, cane juice, dextrose, fructose, glucose, lactose, maltose, sucrose - they're all SUGAR!
FACT: If I eat too much sugar or starch I GAIN WEIGHT. period.
