Sorry I cannot find the thread anymore, nor can I remember who was the OP. It was about Aspartame (I think it was the fact that they had given it a new name to fool people avoiding it) and amongst the posts was a link about bad effects it could have.
For over a year I had felt I had a personality transplant, and definitely not a good one. GP ruled out depression and said I was most probably exausted. I felt tired yes but also very aggressive all the time even to the people close to me that I absolutely adore. Also felt that everybody hated me.
Now I have totally stopped aspartam (I was sweetening most of my hot drinks with it)and a month or so on I am so pleased with the difference. Even the Dcs have noticed that I am "nice" again. In fact I cannot remember having shouted at them in the last few weeks at all.
So again Thank you, a 1000X
