I don't get any side effects, but I did get side effects when I stopped eating all the real sugar I use to consume...headaches, dizziness, irritability (just to name a few). I have to have a substitute if I don't have the real deal or I will go nuts, but I don't consume in large amounts as I mostly drink water anyhow. Gosh, I eat plain stuff as it is, can't imagine a world without sweetness at all....welcome to hell then. }(
