Title: The concept is a good one...
Review: A friend gave me one of these to try at the gym when I told her I couldn't stand to choke down anymore water. It is very good however I started getting a headache shortly afterwards, which only happens after I've ingested an artifical sweetner. Unfortunately the sweetner in this product is sucralose, the chemical found in Splenda. For that reason I won't use this product again.
Is this product review negative?
