medical alert jewelry

Seems like no recent discussion on this topic. Anyway, my medical ID bracelet broke and I want to replace it. I'm wondering what to engrave, however. I'll naturally put epilepsy and maybe "Card with more information in wallet." That's probably enough. But the thing I would really like to...

Do you wear a bracelet or necklace and what alert information do you include? I am trying to avoid getting one of those giant "EPILEPSY" ones, but want to make sure anything important (eg meds) is included, but don't know what's customary.
