Not the answer you want, but for me, I quit cold turkey after smoking a pack a day for 15 years.
The thing that helped is that I wasn't being forced to quit for health or social reasons. I simply realized that all smoking a cigarette was doing was making me not want to smoke another cigarette for 30 minutes. I felt I had no more desire to continue the trend.
The first week sucked. I ended up rolling loose-leaf paper into the cylindrical shape of a cigarette, putting Scotch tape on one end, and poking holes into it so that dragging on it felt like dragging on a cigarette. That actually got me through week 2.
After that, the pull to smoke was far, far weaker. It's weird. It ends up coming in waves. You're fine, you're fine, then you get an overwhelming urge to light up. The need lasts for about 30 seconds and goes away quickly. Over time, the frequency between those cravings gets longer, and the cravings get smaller. At some point, I just didn't feel like smoking at all anymore.
But yeah, the first few weeks are not great.
Best of luck!
Edit: my main advice here is that if you don't feel like you really want to quit, you're going to have a much harder time. If your plan is to taper down, it may be torture. If you're plan is "I'll only show myself this one" every so often, it's going to be a long, drawn out losing process.
