Anecdotally, I found that ease of quitting was inversely related to the amount of pressure I put on myself to quit. I smoked for 15 years and always vowed I would never be a self-loathing smoker. I think so little of my attempt to quitting successfully that every time someone brings up quitting cold-turkey I need to remind myself that I attempted to quit on multiple occasions. - I simply didn't feel bad when a strategy didn't work out.

Ultimately I weened myself off of nicotine by vaping and stepping down the concentration of nicotine over a long period of time. I quit vaping in early 2020.
