I am 22 years old. I started smoking when i was 15 years old. So its been about 7 years. In starting it felt so good to smoke. But now i am fed up from this. My family also knows about this. They also force me to quit smoking. But it is not in my hand, i get craving as i get up from bed in morning. I smoke 10-12 cigarettes per day. I want to quit smoking. Can you tell me how to do?
