What are your experiences with artificial sweetners?

Hi. I'm new, just trying to get some ideas on what foods most of us should avoid. I have been using saccharin since childhood, my whole family has without any harmful effects. I am ok on sweet and low, therefore. But I had sudden and severe reactions to splenda. Since it is put into so many low calorie foods and soft drinks, juices, instead of saccharin nowadays, it has really prevented me from using many of the foods I ate to keep weight down. There was some news media attention to saccharin that had no basis in reality some years back: I don't know why they think splenda is better, but they all went to that. Also, I notice corn syrup is in so many things. Does anyone know what the effects of that are?summer.rain
