A colleague of mine is a social smoker, smoking weekends and a few each evening. She has given up totally now and is complaining that she keeps getting a dripping from the nose into her throat which is clear and keeps having to clear her throat. I have told her that I reckon that this is due to her quitting smoking and that her sinus` are clearing, though she disagrees as she says that she only smokes at weekends when out with friends and max of 2 or 3 each evening, never during the daytime and as so should not experience any withdrawal effects. Over to you guys, am I right?
