I seem to be the only person in the world with allergy (or intolerance?). If i eat potato - the purer the worse it is though even a little starch in a sauce/cake can d the job - I do the following in approximately this order and within 15 minutes - feel a bit edgy or down, eyes and nose stream, constant yawning, disorientation, flustered, flushed, slurring, need to lie down / sleep. Surely I can't be the only person? Could it be related to blood pressure? Similar reaction with vinegar and mustard (though with mustard includes itchy nose / slightly swollen tongue - though a test suggested I am not anaphylactic. I've been like this since birth. Can anyone shed any light?
