i think the reason quite on influence by friends or due to
curiosity.
For smoker, as once run out of cigarette, 1st thing come to ur mind
is go n get a pkt. when do nothing, u will keep on smoke n smoke n
smoke. i tried quitting which last 2 wks, but due to fren
influencing, i pick up again. n smoke more than before. really need
strong will to quit.
