I've also got an insulin passport. Personally I think it is a waste of space, I already carry a card stating I have insulin dependant diabetes, I also carry my prescription exemption card and I always have full kit with me, insulin etc. why on earth do I also need an a4 piece of paper folded up with my medication details on it? I really can't see the point. I am sure someone out there will find a perfectly good reason I should carry it, but I'll take some convincing.
