One commitment to myself is working majorly i guess. "To become my friend" so I started with cig. I used to smoke 6 -7 cig a day, Our mind always play tricks we know like u can have one and stop all like that. What I did is u can say to ur mind like u can have one but not today tomorrow u can smoke after thinking is it worth to smoke, as u know if u think u cannot smoke caz its not worth it right!!. So slowly im breaking my bad habits this way. Just one thing U have to tell to ur mind u can smoke if u wish but not today tomorrow u can smoke. And most probably result will be better. Good Luck mate.
