Mr Nicotine isn't very happy today there are so many stopping smoking, so he will try every trick in the book to get you to smoke again! The reason being he wants first of all to make you really ill and then eventually kill you the latter his preference is slowly he wants to make you suffer.
So be ready for his attacks because they will surely come, and don't give in fight him because he doesn't like fighters, he will move on to the weaker ones but once he has them he will be back to try to get you smoking, but resist and resist he will eventually move on to greener pastures and you will be free. Good Luck
