Several days ago, while rushing to get dressed, I gargled several tablespoons of mouthwash. In a rush, my throat reflex made me accidentally swallow the mouthwash. I've not been nauseated or sick. I called the poison center hotline to make sure everything was okay. When I exhale, I notice that a strange "minty" odor is coming from my nostrils. It was not present before this incident. It is similar to a menthol scent and causes my eyes to water. I have tried drinking a large amount of water to flush my system. I have also tried activated charcoal and liquid chlorophyll, in an attempt to deodorize my lungs. I have not been successful. I thought the menthol mint smell would disappear after a couple of days. I have never smoked cigarettes. Has anyone had a similar experience or have any suggestions? Any helpful insight is appreciated.
