For a MUCH Safer alternative to
Aspartame click here
There are many associated risks with the use of Aspartame and much controversy about its approval by the FDA, at present I will not get in to the details since there is a lot of information and I would rather spend my time at this point on positive things such as Stevia. If you do want more information (which I do recommend because it is intriguing) Then order one or both of the books on aspartame I recommend on the Books Page.
