OK, I'm a former heavy smoker, started at 14 or 15, can't remember. Smoked 3 packs a day at 18. Quit the first time in 1991 for most of the summer. Was in college. Went to a party, smoked one cigarette. Was a smoker again.

I quit again the next spring, and that was it for like 12 years till I was in a gnarly programming gig and I thought I was going to have to divorce my wife, so I smoked again for a bit. Then I quit. I ate a lot of sunflower seeds, the ones with the shells.

But hell, now I chew once a day, except at work, when I chew more, but I can feel that wanting to leave my body too, as I could keep em in all day before and now they just get gross really soon, like way too soon, and when smoking was taking it's leave of me it felt the same way...

Just believe you can do it and you can do it. Nicotine is a water soluble molecule meaning it will pass from your body within a few days and after that it's all just a mind game, no more real cravings.

It is doable, you're not the only one that has done this.

Good luck, the internet is way better than cigs anyway.
