I personally know I have aspartame poisoning. I have drank soft drinks with it in it for years, like 8 a day. I have loss my short term memory, have some hearing & vision problems now, anxiety/panic attacks, intestinal problems & abdominal pain, can't think clearly & sometimes can't speak plain. This is serious! I am quitting now! This POSION shouldn't be on the shelves! http://www.aspartamekills.com/symptoms.htm
