Thanks Mama
I think I might go with the picture card idea. I was thinking that would be the best idea anyways, it will probably minimize the risk. And no, I don't have to carry an epipen, my allergy is more like an intolerance, but still, I don't want to have to spend a day in bed recovering!
Also I am waiting on Yakkan Shoumei to arrive because I have to take pills with me. Anyone else that needs to take medication, I thoroughly recommend completing your application and emailing the pharmaceuticals inspector to ask if it is filled in correctly. They were extremely helpful.
