Years and years of struggling with quitting because my brain never really hit the zone where smoking itself seemed unappealing and now somehow out of nowhere the stench is absolutely disgusting. Like my boyfriend comes home smelling of cigarettes and its so intensely gross i have to breath through my mouth. The offer of a cigarette doesnt work as well anymore i think i finally hit it folks i might actually be there. My lungs ravioli rejoice
Congratulations! Same thing happened to me with booze a while back, I just suddenly soured on the whole idea.
My unsolicited advice is to write yourself a little note or letter on your phone about how good you feel after a few days/weeks off. Reading it back has saved me from random urges quite a few times over the years.
