I don't have any allergies that I am aware of but a close friend of mine does which makes travel a nightmare. He has to make sure that anywhere he eats is 100% clear of his allergies which is not always possible.
I have a slight allergy to certain kinds of seafood. Nothing severe. I can still eat most items but if I have too much I break out in a mild rash that lasts 1 to 3 days.
I have some but I don't like to share them online or with anyone. You never know how people can be. Like one of them is so severe that it could kill me and if I ever got on someone's bad side, they would have an easy way to end me!!
I have a mild/weak peanut allergy. I can eat peanuts (and nuts in general) but I have stomach issues when I do. I don't get a rash or have trouble breathing like more severe allergies.
