Welcome Jeff! At some point, you are going to have to reach deep inside you and find something other than the fear of death to keep you quit. You will soon lose your fear of getting cancer.
I quit simply because, after using tobacco for 38 years, I was tired of it and wanted to quit. I now put this desire to remain quit, my quit, on a high level of importance. My quit is as important as anything else in my life. Fock cancer. I don't even think about it. I do think about my quit though, every damned day. Every day, I commit myself to my quit.
This is what it takes.
