Had to send in my personal experience before stumbling off to bed. I did have neurological symptoms that I feel were the result of consuming sugar free desserts and drinks sweetened with Aspartame.
I had muscle tremors that made it feel like we were having an earthquake when I was trying to go to sleep at night. Since I completely stopped consuming any of these products the last 5 years I have had no shaking sensations.
My son gets zero of these products. I noticed that when I ate desserts sweetened with Aspartame the tremors returned. I think the stuff is VERY questionable.
