I lost my mom in 1999.
To this day I still have the memories/thoughts connected to what things my mom cooked prior to the 40 years I left home, 39 of those years my smoking years..
They are interconnected to the time of year, temperature, what produce is in season, the smells.
It's connected up there in our heads.
Those connections are many many times stronger than any memories of smoking.
You can simply let smoking go.
Smoking is just something you did along with living until you see it's control over you.
Unlearn smoking. It's easier than you think.
Give it time.
