Unfortunately, my own husband, Ken, was one of them. Late last summer he was having a bad headache located mostly on one side of his head. He went into the Univ. of Utah Medical Center for an MRI. They discovered a mass, more like a brain lesion. The Dr. who first examined him up in Payson (a town located between us here in Price, and closer to Provo) is a specialist in those sorts of problems, and recommended the MRI.
Anyway, Ken cut out drinking the Diet Coke or anything at all which contained Aspartame or other artificial sweeteners. His headaches soon stopped, and when he went back for another MRI in early Feb. everything was clear, no more brain lesion, or beginning of a tumor or whatever it was. When I contacted the Dr. again by E-mail about a month ago, he said that several of his other patients, who had also stopped drinking any diet sodas, had all of their similar problems cleared up, too.
There are several other articles which I posted last fall, perhaps when you were away from the List. Among them was one describing how Japan had banned all Aspartame for the last 10 years or longer.
STEVIA is being used instead, and Japan is now cultivating the sweet-leaved bushes there.
