Disclaimer: I am NOT a Medical Doctor nor do I play on on TV, not even in a Soap Opera.
I am sharing MY experiences and what has worked or not worked for me. IF anything I write sounds like something you experience, I suggest you find an Allergy Specialist that is willing to work with you, or a Doctor that won't think you're crazy. Yes, I am serious with that last statement. Sulfite and Sulfate Allergies are NOT something readily understood or recognized by most medical practicioners at this time. We have a community of folks online that are working together to educate ourselves and others.
I hope that you are able to get some information here that will help you feel better.
