You may be able to reduce your sensitivity to the sulfites by taking Vitamin B12 orally before any meal containing sulfites. Other nutritional components necessary to support sulfite metabolism (yes, we have an enzyme to process sulfites since sulfur amino acids break down into sulfites and sulfites are harmful to the body so the body wants to change sulfites into sulfates...but this enzyme can become deficient or inefficient in certain situations): Magnesium, Zinc, Iron, Molybdenum.
I've also had Vitamin B12 orally help counter-act a sulfite reaction if I get the B12 early in the reaction. I carry B12 with me everywhere because I never know when I'm going to get a blast of sulfite from somewhere. There are 6 different sulfites used, one of which is sulfur dioxide. Sulfur dioxide also is present in automobile exhaust, and often in the emissions from manufacturing plants. I get horribly motion sick if I don't have regular intake of B12.

I hope this helps - take care,
