I believe that I have suffered some of the effects of Aspartame after being a Diet Coke drinker for over 12 years. It began with symptoms of insomnia and then severe joint pain. I am currently being treated for rheumatoid arthritis, but I eliminated Aspartame completely from my diet about two weeks ago. I have noticed a marked improvement in my joints and I have also lost about 6 pounds. I understand that it also causes weight gain in some people.
I am very interested in more information on this subject and am prepared to help spread the word.
