I think you are asking about my daughter. The most helpful med has been Cromolyn Sodium taken before meals and at night. She also does not eat much at night. She finds that it is better to have the stomach more empty than not. She also takes antihistamines. I don't know which ones. She takes a lot of meds. Not all for mast cell. There is not a cute. It is matter of management. She avoids dairy and used to avoid gluten but seems to be able to handle some now. I know some people have a very narrow range of foods.
