The way I finally knew I'd kicked the addiction was when I could have a beer with no desire to light up. It took over a year.
Drug addicts rarely, if ever, have success unless forced into a rehab facility. This is only after numerous arrests. Usually, for robbery, murder, etc. If I'm not being too personal, what facility did you go to? Have you spent time in jail for committing crimes to buy cigarettes? 90% of drug addicts spend time in jail for committing crimes to buy drugs..
If I'm reading your point right, you deny that nicotine dependency is an addiction.
Nobody needs a facility if they decide to change things, and stick with their decision. When I got tired of coughing up brown slime for the first few minutes after I got up in the morning, I started to think about quitting. When, one night after the stores were closed and I had no change for the machine in the lobby of the building I lived in, I found myself scrounging through my car's ashtray for a smokeable butt or two, I made the decision.
A few miserable weeks, a number of months of occasional cravings, gradually to "boy, a butt would be great with this beer". After 13 or 14 months the desire was gone.
