One cigarette makes my throat terrible

It is hard to cultivate a good habit.
Since three months before, I have cultivated the habit of no smoking. This habit makes my throat not terrible any more even I shout to my students; When I dine out, no smoking allows me more time to eat the dish, so I now hate smoking.
Yesterday we wanted to light a mosquito-killer-aramaticness, without a lighter, so we use the gas to light a cigarette, and in the process I smoked a few times, just for the cigarette to burn more smoothly.
But in the second morning, my throat was not comfortable, so I knew that breaking a good habit is not acceptable if you want yourself develop each day.
From now on, I will not smoke any more!
