hold tight for 6-10 months

Hold tight for the rest of your life.

You have overlooked the "habit" and the power habitual associations will have over you for the rest of your life. The nicotine is out of your system in less than a week but the habits associated with the nicotine will remain.

The only true words of comfort when confronted with the habitual urge...it will pass.

[Eric in the Ozarks]

I quit cold turkey in March of 86.
I kept it a secret from friends and they didn't notice for about three months. Then, someone said "Eric...you're not smoking ?"
At that point, most of the habit was under control and friends supported me.

I talked to a guy who had been smoke-free for thirty years or so and he said he still would love nothing better than a smoke.

Yes, it will pass. You need to distract yourself each and every time you want a cig for the first couple years. That distraction can be as simple as deciding to brush your teeth, channel surfing or checking the weather online etc.

I used to smoke 3 packs a day and the urge lasted for 7-8 years. Don’t be discouraged - by lasted I mean it was down to wanting one 2-3 times a YEAR by then. Never want one now. No matter the situation - stress, others smoking around me etc.
