I am one of those people that had to work out myself what was wrong with me because all the doctors I went to didn't know. I even had one doctor so exasperated he offered me an anti-depressant! I went through so much trying to find out what was wrong with me. And the doctors were no help at all. After a few years of reading newspaper articles and looking at what I ate I finally worked out my problem - that being preservatives 202 and 282. It was so good when a doctor listened to me, agreed and sent me to a dietician who agreed as well. I was then able to get my life in some semblance of order. - Maria, by email
