Sudden-onset Food Allergies

[tamaranth]

Wednesday: had Standard Werk Lunch #3 of Ryvita & Whole Earth peanut butter. By 2:30 felt really ill (vomitting, dizziness, slight visual disturbance, overheating). Ended up going home.
Thursday: dozed in bed. Symptoms cleared.
Friday: had Standard Werk Lunch #3 of Ryvita and Whole Earth peanut butter. By 2:30 felt really ill (vomitting, dizziness, slight visual disturbance, overheating).

Is there a pattern here? Has anyone else experienced sudden intolerance of favourite foods?

I should add that I've been suffering from more-or-less constant low-level stomach upset since late November. This is different, or at least a different set of symptoms.

Neither Ryvita nor peanut butter (nor nuts in general) have ever bothered me before.

I've not had that experience, but I believe it's fairly typical of allergies that they are triggered by proloned/repeated exposure.
