getting colds or flu after quitting
Also, with nerve cells that have now regenerated throughout your whole respiratory tract functioning normally, you can feel pain and irritation that were dulled when you were a smoker. It may have taken you a little longer as a smoker to even know when you were getting sick. With impaired nerve cells you may not have felt earlier symptoms, or if you did you may not have been able to differentiate what was just an effect of smoking too much or of actually having some sort of infection. With nerve cells back in place you are likely not going to be overly tempted to smoke for the concept of pouring hot irritating smoke on an already irritated throat is generally not a pleasant thought.
Where you do have to be careful and aware is that when your cold starts to dissipate, you might get stronger than normal thoughts for cigarettes. For while you likely cut back on cigarette consumption when you were a smoker with a cold, when you started to get better you would have to make up for lost time, or more accurately, for lower than normal nicotine levels since you had instinctively cut cigarettes down to a bare minimum in those times. This makes the first time getting well a potentially powerful trigger. Just be aware of the fact and it will help you to minimize the effect. Then know that over your lifetime, your colds will probably be less frequent, resolve quicker and be less severe as long as you always remember to never take another puff!
