By the time I decided to quit smoking, I pretty much bought cigarettes exclusively from one convenience store 2 blocks from my house.
Buying smokes was part of my preparation for the next day. I would go after work and fight through the 30 school kids getting their snacks before they were bussed back to who knows where because I was already off to work before the store was open in the morning.
The guy at the register would always pull two packs down from the rack when he saw me walk in the door no matter how many high schoolers filled his store. Addicts rights??? LOL. I'd put my money on the counter and off I'd go.
When I quit, I knew I should probably just avoid that store. The day I bought my last pack, I told the owner I was quitting smoking. His jaw dropped like I'd just denied his kids their college education. I don't think he believed me but, we lived in that neighborhood well over two years after I quit smoking and I never went into that store again.
I like to call it COMMON SENSE.
I knew two packs would be put on the counter if I ever walked through that door again.
I'm sure many quits have been lost simply by doing what I avoided doing.
You must make some changes to avoid temptation after you quit.
If you are new to quitting I suggest you "smarten up" and consider where your temptations are before they slap you in the face and ruin your quit!
You cannot quit and remain the same. It just don't work that way. :-)
