Well cold turkey happened to me, I didn't plan it, I just decided to stop smoking and got through each day by that state of mind then a week later realized I didn't use anything to quit like I wanted to. If smoking is on your mind all the time a smoke aide may be helpful. I work at home and this was also a big obstacle because no one could stop me or look down at me at home(only ME). Honestly I think its the environment. Once I moved then I was more confident to quit..so maybe change around your house, throw away the smoking stuff,ashtrays, anything linked to it, Get some air freshner, candles, stay away from the friends that smoke. STOP smoking in the house, go outside, this will definetly segregate you and then you'll start to think about what your doing... that helped me alot when I was trying to quit. Everyone at this site is here to help other will give you more tips, advice and support if this doesn't help...
keep in touch and let us know how it goes
