Something to pass along; eventual success in quitting smoking is correlated with the number of times you try, not how successful you are on the first attempt to go cold turkey---so keep trying.
Once you quit, the cancer risk clock starts counting backwards (assuming you haven't had it already)---and at 5 years after your last puff, you re-set to the baseline risk of folks who haven't smoked before.
And---the people who love you want you here as long as possible. So, look for the support you need and best of luck..
