I'm sorry you are having so much trouble quitting. I believe it is one of the hardest things I've ever done, however, the patch worked for me. That and playing my GameBoy full time. I don't really have any other ideas, since you've tried so many already. I have done what you have done and started back several times after quitting but I had my last May, 1993 and am ever so happy I did. I watched my mother die of COPD to which smoking was a big part of the cause. She quit but too late. Keep trying you will find your own way and you will be free again. Good luck to you.
