Dear WangLin
How are you doing?im sorry to know that you are addicted to nicotine.As we all know that it is really harmful to your health. As shown by the statistics more than 30 million people died every year because of this evil stuff. You are now paying money to buy yourself damage! If u don't how to give up smoking there is somethinig i can teach u. First, find it a subsitute, such chewing gum or chocolate, when u wanted to smoke eat those food it can help u to move ur focus away from ciggerates. Also u can hire a personal medical care to take care of u and to supervise u not to touch it anymore. Last, my dear friend i am really hoping that u can get rid of nicotine and be healthy again.
