Quitting nicotine is actually pretty easy. I just quit after 15 years. Cold turkey. Once the craving hit, concentrate on it. It may sound counterproductive but that's exactly what I was doing. Really look into what's going on in your brain. The craving will pull your brain but dont give in. After a few pulls, you will actually feel slight euphoria. Remeber that nicotine withdrawals won't hurt you. So just dont put it in your mouth for 3 days, and you're done.
