I can attest to the fact that Aspertame and MSG can cause ALL those reactions and more! There are some there that I didn't know though. Check out www.truthinlabeling.com and REALLY be shocked! The H1N1 vaccine had MSG in it!!! MSG goes by many names, too. That website will tell you what to look for.
20 yrs ago I was just this close to going on disability. I was unable to walk - in a wheelchair, unable to know what people were saying to me and God Help ME, I didn't know who my boss of 7 yrs was. I was going blind, you couldn't touch me because I hurt so bad. Then we discovered MSG was the culprit. Now --- I do every imaginable craft, I garden, we travel....I'm healthier than a lot of people my age (I'm 60)....I tell you this - because some people don't believe what those additives can do to you. I DO find food to eat....I'm 40 # overweight so obviously I CAN find food without the additives!
