I despise fake sugars. However, I just bought some stevia from Trader Joes and have used it in two things: a tiny bit in my tea, which is wonderful and I do not miss the sugar at all; and in the allowed dessert on Phase One of the South Beach Diet, which also tastes very real and yummy. (That dessert should be known to all: you take ricotta cheese, put it in a bowl, and mix in a tiny bit of stevia or other substitute and a teaspoon or less of unsweetened cocoa powder, a couple of drops of vanilla, mix well, and eat! It doesn't seem like diet anything! Yum!)
Anyway, stevia is not fake. It's just a sweet plant. Not bad at all.
