I struggled a lot in the early months of my quit. With time the thoughts of smoking have become fleeting, but they still happen. My triggers are stress and I am a very anxious person so when the stress ramps up a crave still happens. They don't last long and I've learned to deal with them. Even at 2 plus years... Thoughts of my past smoking life creep in. When this happens I remind myself of the reason why I love being a non smoker. I remind myself that as a smoker I could not ever get enough. I wanted to smoke another before I put out the last. I won't live that way again. I do follow NOPE for that reason. No matter what I will not smoke. I made this commitment to myself and I know I will not break it ever.
NOPE works for me but you do what works for you. I know many people who have long quits and have never even heard the words NOPE so I won't say it cannot be done. Whatever your way, you need to embrace it. You need to make a commitment to yourself to keep your quit strong. You're worth that effort and you deserve to the have peace and freedom that comes with not needing a fix a 20 minutes. If Chantix is what it takes at any time, take it! Whatever works!!
Very sorry about your mother.
