Quitting isn’t very hard if you've got a valid reason, determination and, most importantly, you set your mind properly. Don’t do “strong will” quitting where you force yourself to go through painful experience of quitting, but you don’t fully understand why you have to. Your mindset is the key - if you start to truly believe you don’t need tobacco and there’s not much that you sacrifice by quitting, it comes naturally and you can call yourself a non-smoker from day 1. You must be certain that there won’t be any reasons to feel there is something missing, you no longer have your daily ritual, you don’t have chat with smoking coworkers or you don’t know what to do with your hands. No matter how hard it sounds to imagine now, as a non-smoker you cannot care less. The typical imagination on how hard it is to change habits or how nothing is the same after that change, you must remember that your mind projects that to you in a very hyperbolic way. Same goes as the physical aspect of nicotine addiction - some say that your body would absolutely freak out if you suddenly remove nicotine from it. For the most part, this is utter bullshit. Yes, you can totally perceive nicotine hunger, but it’s there only for as long as there’s some nicotine left in your body. You only need 10-14 days to get rid of all of the nicotine and that’s it. In practice the hunger isn’t even as bad as smokers typically make it out to be. The mental addiction is much harder, because if you stay addicted and keep feeling as you were robbed out of something you liked, you can go back to it even after long time, even if cigarettes taste like shit and make you sick to the stomach and you want to vomit and poo at the same time.

I’ve quit smoking multiple times, sadly you can go back to it after some time if you decide to experiment with it to maybe teach yourself to be “casual smoker” (which you won’t be, believe me), or like in my case smoking weed mixed with tobacco has put me right back in nicotine addiction. I’ve quit smoking 2 years ago now, I was sick of that shit.
