I'm somewhat allergic to cat and dog hair (convenient, I'm currently living with two dogs and three cats, one of which sleeps in my bed) - I take antihistamines, but I'm also on steroids for my SLE and I think they're what keep me from having a bad reaction. I'm very mildly allergic to pollen but that only affects me when I go home (surrounded by fields) - living in town it doesn't bother me at all.
No food allergies, mildly intolerant of lettuce, every now and again I eat a bit out of politeness (and embarrassment at being The Fat Girl Who Won't Eat Salad) and remember how rotten it makes me feel.
