Ok so this may sound gross..sorry.. so i quit smoking a month ago and i was not coughing anything up which worried me b/c other people said they have coughed stuff up after they quit and it was the "lungs cleaning themselves" etc so i was worried b/c i thought my lungs weren't cleaning themselves. So today i drank 2 cups of hot tea and then when to the sink and was trying to cough stuff up and i eventually threw up and what came up was mucus/phlem (i had an empty stomach except for the tea) but the mucus/phlem was like a mixture of being clear and brown..it was gross..and i'm worried b/c i know having brown gunk come up cannot be good but is it possible it is brown b/c of the 2 glasses of hot tea i drank? i'm confused and worried
