I finally quit smoking when I was 67 after my cousin died with throat cancer. I started with nicotine patches as directed for two months, then the next box of patches, I cut each patch in half until it was gone, then the next box I cut into fourths, the next box eighths and etc. It took me seven months by doing this but I am proud to say it was successful. My sister and brother had already had lung cancer and I had cut back to 6 cigarettes a day for several years before I tried the patches. That was 17 years ago.
I agree nothing is harder and you have to want it for yourself.
