If you can spare the time to watch it, there is a documentary online called sweet misery, if you google it you will find it. i found it and thought it was well done & informative. There is also a long peice about how it got approved (fishy) for human consumption in the book skinny *****.
i personally don't use it after learning this information, but i drank WAY too much diet pepsi, it was an addiction, or at best a bad habit, and i knew it was too much.
i say if you are worrying about it, it's not worth the worry, just skip it. JMHO.
