Keep a symptom journal. Learn to recognize the smallest of changes in your thinking or how you are feeling. Early detection can be the key in getting your ammonia level down quickly and easily. There are wonderful HE support groups on Facebook, get connected with people who know and understand exactly what you are going through. You are not alone!
Educate yourself and your family on what to look for and how to help you if you start to have an "episode". Don't be embarrassed, it is a disease not a problem.
