For me, stopping had to be sudden, pretty much. Tried longer tapering a few times before it stuck. Used a patch briefly so I wouldn't be miserable, then nothing. Rough first few days but it passes quicker than you'd think. Once nicotine stays in your system, you're feeding the addiction pathways. Lots of people succeed with gradual reduction, but some of us are just wired for all-or-nothing (guilty). Cold stop or close to it might be the play for people with that kind of profile. Won't work for everybody, but if you've got a pattern of addiction, it's worth considering.
