Yeah, my and my SO have very different experiences regarding this.
I’ve quit cold turkey several times with little problems - quit for several months or over a year, then used again for x months, then quit again, etc. (This went hand in hand with a certain seasonal job.) Apart from very slight ”I wouldn’t mind a smoke” kind of feelings it doesn’t have much of an effect of me.
My SO was miserable, depressed, craved cigarettes for months and months. For the longest time she was convinced that it isn’t possible for her to quit, since they cravings didn’t go away. (Until they did.)
