Hello, looking for people who have quit and having similiar symptoms like myself....I quit this past Feb, I became ill with I think was upper respiratory infection, have been on a errible roller coaster since then. I have not had a ciggerette since. I have been sick for 5 months with terrible mucous in my bronchs and throat, choke all the time, bad sinus drainage have been to the doctor so much they are tired of looking at me. They did a cta scan on my sinuses and lungs could not find anything...did copd breathing tests, those came back neg. but I choke on this chronic mucuos constantly. finally the doctor did a bronchcoscopy...and seen he mucous and washed it out. Went today to talk to him about the procedure and he didnn't find anything but extreme mucous, but he said quitting smoking would not cause all that, I would have a little from quitting but I would not have it for this long....has anyone else gone through this before?
