I quit smoking three years ago . I was a chain smoker for at least ten years say sixty to seventy cigerrates a day.earlier as various occassions and now at some occassions say at least three four occassions a year i face a strong urge to smoke though i successfully resist . i feel less cough is it a bad symptom . I also has problem with heart as heart rate increases at occassion twice in three years at 220 pulses.will it improve by time or some specific treatment for post smoking is recommended and will do.
