<<Disclaimer: Verify this information before applying it to your situation.>> I've just read a message from Jody about always carrying Alka Selzer Gold with her to deal with reactions. A great idea. I've done that for years, but have had so few reactions in the past five years I didn't need to use the tablets. Then, two years ago, I was fed something at a doctor's house that was supposed to be gluten-free (he was the cook!) and had a reaction. (It was caused by a stupid seasoning he used in the chicken.) I took the A K G and got sicker. Two days later I read the dates on the little packets that were still in my suitcase and realized that they were past the date on the package, so I caution all of you to check the dates on your Alka Selzer packets once in a while, and throw out the ones that are outdated.
