to start out try a food diary. write down everything you eat in a day. note down when you have your symptoms. in time this can help you see patterns. you could have a problem with a food allergy or you could be getting some kind of cross contamination when you cook. if the food diary doesn't show patterns a doctor will be able to rule out other possibilities. it might help to note down times you are stressed out sometimes that can cause problems too.
