It's probably not the corn in the tortillas. Corn tortillas are routinely sulfited to preserve or whiten them.. Check the label. The refrigerated ones might be ok.
You might be ok with a little bit of milk chocolate, but definitely avoid the yummy dark stuff. You need to find out your tolerance level.
In Rick's free online book there are some pages that show you how to calculate how much sulfite is in a particular food. It's helped me a lot. I know I can have most of a can of soda, but definitely have to stop there and avoid any other sulfites in anything else for the rest of the day.www.learningtarget.com/nosulfites/index.htm
Click on the ebook and start reading the next 3 chapters. You can find in his tables how much sulfite is in many of the foods you eat. I start reacting at about
2000 micrograms (not milligrams). Rick recommends keeping the food journal too!
Keep on with the allergist! No, it shouldn't make things worse! Do make sure he knows how you are testing yourself for sulfites. If you need to do "challenge testing" he'll want you to do it in the office. That's the standard allergists are told to follow now. You can look up one of my old how to do challenge testing posts in the search box at the top of the page. But I'm not recommending to do it at home, especially if you have a serious reaction. I get tachycardia as a reaction, so I have to be careful with these tests.
You have allergies besides sulfites. I love not having to take allergy meds, some of which make me sleepy. The shots have made a huge difference in my other allergies! Shots won't help with sulfite intolerance, but you might as well be more comfortable with the others under control.
I keep an Epi-Pen, but it's because I also have a "true" allergy to some meds, and sunflower seeds, which can be hidden in cakes,
cookies, just about
anything. I can probably get away with just having Benadryl and Alavert tablets on hand at all times. (No Benadryl liquid - sulfited)
Take another look at some of the herbals you are taking. St. Johns Wort, in particular, is known to interfere with lots of meds and conditions.
