I am 47 years old working lady. My health is OK. whenever I take my meal, after 15-20 mintues I started coughing and within 4-5 mintues I vomit and after that I feel relaxed and my cough is over. I am alergic to dust, fumes, cooking smells like making of vegetables or fry something. Please advice. I am not fat and my weight is 61 Kg.
