I know this question is old but thought I would reply anyways.. Yes... the 8 month quit that I ruined, immediately after I seemed to get sick with everything under the sun. This time am not feeling too great either, but it is probably b/c smoking has killed your immune system to some degree all these years and it is finally gonna start fighting back!
Stacy: The stuffy head and nausea are not from the nicotine withdrawal. You are actually sick with some kind of bug, independent from the nic withdrawal. I was sick with a bad flu bug while quitting. It's actually what made me quit. It did suck, but it also probably had its advantages. I spent the better part of my first few days curled up under the blankets in bed.
I had a slight cold on my quit date. My cough was starting to clear up but as more days pass that I don't smoke (10 days today) my coughing seems to have increased and is more productive. My guess is that my lungs are trying to clear themselves but I'm making a doctor's appointment to be on the safe side.
