I have to say, after trying Stevia I was terribly underwelmed by the results. I tried it in oatmeal and never got a sweet taste. I don't drink any thing excet water and plain carbonated water, so I have no need for a sweetner any more. I have given up oatmeal, because it is only good sweet with butter and cream. I would rather do with out than settle for a dim substitue. It did not give me a headache. My 2 cents
