Nurse2Pilot, I haven't in the past, however a stipulation of the OML is that I carry 2 during flights in order for the medical to be valid. I have never had to use an Epipen.
They have been my exact thoughts from the very beginning of this medical calamity. I know of my allergy and the best ways to avoid a reaction and this greatly reduces my chances of having one, but other pilots they may not know of an allergy they have, have an anaphylactic reaction and don't have any way of dealing with that situation in the cockpit. People can develop allergies or other medical conditions at any stage in life without knowing about them. I may consider this argument if I decide to try and get the OML removed at some stage.
