eclecticgemini just answering your question that I saw on 30s somethings quitting... YES, coughing and mucus can* be a nicotine withdrawl symptom. What is likely is that your silia (sp?) -the tiny hair like structures in your lungs- are starting to work again ..they're cleaning the lungs out -thus mucus and coughing can seem* to get "worse." This will start to go away ...between 1-9mo or sooner. Drink lots of water; talk to a doctor if necessary. -just saw 31days quit. NICE!
