A well meaning (I guess) friend kept sending me an e-mail about Aspartame and MS, hinting diet soda. I never drank any and have PPMS and am firmly sitting in a wheelchair. Never ate any "diet" food in my life. I consider it an "urban" myth type of thing and no one sends me such nonsense anymore. I don't think synthetic sweeteners are good because of other reasons. I think the cause is much more complicated IMHO.
