I have never had problems with this before, but I had some eggs the other day, boiled and deviled, and felt a bit nauseous after. I don't know what caused it, and I can't seem to find anything proper online that explains it. The closest might be a sensitivity or an allergy, but I couldn't seem to find enough information on it. I plan to talk to my doctor, but I've been looking to find a way to turn this nausea around before long car rides. Or, really, car rides at all.
