Those don't really sounds like allergies but they sound more like intolerances. I would recommend seeing your gastroenterologist not just your general doctor to discuss this.
Thank you for your response. The reactions are
1. I don't sleep for three days and nights sometimes while its running in my system
2. It goes to my head and I can feel something shrinking in my brain as time goes and on the last day I can feel it the size of a pea and when that goes I know my system is clear and I feel like doing anything, cleaning the house, running. just full of energy
3. My ears and head ring and its terrible
4. My concentration goes I can't absorb anything if I'm reading a book for example, I literally can't function
5. Everything I eat has to be cooked in vegetable oil. If I eat even chips from a chip shop,, for example its no good and one day I was in a chip shop and I saw the fat they use and it explained the reaction. My condition is quite acute and my body just picks up anything
6 A couple of years ago I discovered Piriton, an antihistamine, by chance, it helps me with sleeping and calms my body down.
Welcome to the gastroenterology community! What do you mean by making you very ill? You probably don't have an allergy but intolerances. Have you had a RAST blood test?
