Has anyone been using Stevia and had any side effects? I've read some people say that if its mixed with sugar alcohols it can cause diarrhea, but thats the sugar alcohol, not the stevia from my understanding. I don't want to eat too much of it. Im trying to lose weight, but i know i will still want sweets when i go to like the movies and stuff and so i was gonna buy some candys that have stevia leaf extract but its expensive and wanted to see if anyone had any experiences with stevia leaf extract before i spend the money. thanks
