Well, I'll tell you this story, don't know if it will help or not. When I was a kid my dad dipped and me and my mother hated it. There were spit cups everywhere, we just hated it. We begged him to stop to no avail.
One night, I was at the table eating dinner and I was eating corn on the cob. I was about 10 I guess. My dad saw it and said "Hey, give me a bite of that" and took a bite of my corn on the cob. Apparently he had chew tucked in his mouth because when he put it back on my plate it was covered it brown slime and chew bits. I saw it and immediately threw up my dinner all over my plate.
My father felt so awful that he literally quit at that moment and never dipped again.
Now of course we laugh at the story, but maybe if you think of something personal like that, how it affects others, etc., it might inspire you.
I smoked for years and quit almost 10 years ago now. It was REALLY hard. I had tried gum, cutting down, etc., but I finally had a realization: I was always waiting to be "ready". One day it dawned on me that I'll never feel ready. Once I came to the simple realization that quitting was going to suck, I accepted the reality and quit successfully. When people would ask "how I'm doing with it", I'd say "LOUSY!", but I'm doing it. I kinda took the AA one day at a time approach, only it was more like one hour at a time. And it really did get easier and easier, after the first week or so.
Hope some of this helps, I wish you the best of luck.
