Im smoking cigarette so much.daily 20+ ciggarette.i was starting before 2year ago.how to leave smoking.

Smoke cessation prog: There are nicotine patches or chantix. They also have smoke cessation programs in hospitals. Good luck on quitting. Two years is not a long time so hopefully by quitting now, you are ahead of the game.

Cold turkey.: As far as quitting without any nicotine replacement, the cold turkey method is great. But plan it ahead of time. Pick a quit date in advance, maybe a meaningful date like a birthday or holiday, and gather people who are aware of your attempt that you can call upon for moral support if you start to falter. Good luck!!
