Honestly I don't have any great advice to give you. It was the hardest thing I have ever done...I still have cravings and it has been months and months since I quit smoking. I went 3 years without smoking and then returned. For me it is an ongoing battle....esp. since I am surrounded by smokers. I just try to do other things to occupy my mind and when I used to have the MAJOR fits to and wanted to smoke badly I would just smoke a little cigar.... I don't know if that is a no-no or not but it is what helped me. Good luck. I know how difficult this is.
