I had this happen today to me! I am not going thru a flush but have always been healthy. All of a sudden a feeling like something in my throat and I cough and blow out at the same time just a little and smoke like type thing just flew out of my mouth. I don't smoke, never did! It stunned me and so I drank something right away. it took awhile for the feeling of something in my throat to go away. I thought maybe I was going to all of a sudden catch on fire and that really shook me up!
