It is possible that you may have had aspartame poisoning, but what troubles me that you have probably not got this verified/examined by a medical expert. You may know your body but a doctor is certified to diagnose such conditions and perhaps may give you a correct diagnosis.
A qualified doctor would also help you understand whether this a cause of aspartame toxicity, and how long it will take to get detoxified.
You may get further information on aspartame at: http://en.wikipedia.org/wiki/Aspartame
hope this helped.
I have been thinking this as a possibility for the past week
about 7 months ago, I had the most severe itching of my life..scratched til I bled..all upper arms
well, last week it started again and it will not reside
BUT, I have been chewing sugar free gum for years..is it possible for it to just develop no?
its the only thing I can think of
