Thanks to your book Fed Up I discovered at the age of 17 that my chronic hives were due to dietary salicylates. But it wasn't until I inadvertently took an aspirin tablet at the age of 25 (it was the first time I'd ever taken aspirin - in the UK they are packaged to look the same as a paracetamol packet) - that I realised how sensitive I am. As well as the usual hives, my face and throat swelled so much I had to hold my head right back in order to breathe. (WARNING: salicylate responders beware: it is possible to die from one aspirin tablet. If this happens to you call an ambulance or have someone take you to the nearest ER as quickly as possible.) – from Fedup Roadshow 2012
