There is a member here who had an episode with anaphylaxis that she thinks started her phobia, I won't out her, but it had something to do with peanut butter and she can share her story if she would like....it seems like a trauma plus something that might cause v*, so it would be a good candidate to kickstart a phobia. That's all you need, an association of something, anything with v* that is more traumatic than the average person (who mostly already hate v*) and then with the right combination of genetics and environment (we assume) you could be off to the races. Do you know your allergens so you can not have that experience again?
