I have used Stevia for over 20 years now. It is indeed a great substitute for those with diabetes. It seems like it is very expensive since it tends to run between $40 and $60 a pound, but it is so super sweet, it takes very little.

Less than 1 teaspoon will sweeten an entire gallon of tea. One pound lasts me almost two years, so the cost is actually much less than the cost of sugar or any artificial sweetener.
