I'm sorry to hear about your plight. And whilst I fully realise how unpleasant a nut allergy is, I'm truly glad that I don't fly with anyone who has one. To be incapacitated in flight for due to a nut allergy is not acceptable. There are too many sources to contaminate crew food and I think the likelihood of ingestion is too great a possibility. When your medic confirms that you'll neve, ever need an Epipen, that'll be different. Unfortunately, this isn't a normal job.
