I "quit" cold turkey about ten times before I was actually able to "quit". It is not an easy task, but it is possible. The cravings used to come all the time until I came down with a crazy bad case of pneumonia a few years back. Ever since then, I have not had cravings. Take my advice and stay away from any psych drugs to stop smoking. They can be quite harmful if you have any history of depression or anxiety but have not been diagnosed. Primary care doctors should not be giving any mental health drugs and should refer you immediately to a mental health physician. I personally smoked for about 13-14 years. The smell of smoke on someone to me now a days is gross. I still go to bars where smoking is permitted by law (small amount of food sales). I don't complain second hand smoke even though I absolutely hate it. I don't allow anyone to smoke in my home or any of my vehicles. I laugh when I see people standing in the rain or freezing cold weather having a smoke and remember when I did that. I can't stand when people smoke right in front of public entrances and am glad smoking in public places was banned here in Pennsylvania. It actually helped me to quit.
