Ethansmom stated that she wears a MedicAlert bracelet. I forgot to mention that I started wearing one at a time when I was still driving. It does provide a degree of security because access to information regarding medical conditions, medications, allergies, family and friends and doctors is available. So if you get into trouble and can't talk, the staff at MedicAlert can do it for you. Just have to keep your file up-to-date. They also have necklaces if you want something less conspicuous. The bracelet is so light weight that I am usually not aware that I am wearing it.
