The real challenge is that the difference between one cigarette a day and zero is huge, at least for me. Once you are at one cigarette a day, and e.g. commit to it being after a workday, you start waiting for the end of workday. It's easy to start feeling that the day does not begin until that moment. Real withdrawal starts at around day 3 and takes roughly 21 days for me.
I think smoking cessation products like patches and gum is not really helping either. It's still nicotine. I have wanted to try Varenicline, but it requires a doctor's prescription and (seemingly) "strong enough" dependence. I have hated the idea of paying 100 euros for a doctor's appointment to maybe get a prescription that costs me another 100 euros.
I plan to quit nicotine for good next month, when I submit a dissertation. After roughly 7 years of using snus and nicotine pouches, I have noticed that my gums are retracting, and when I eat food, a lot of it gets stuck at my lower teeth, and there are gaps between my teeth. I would not be surprised if I need braces, and in part wish that would solve the problem -- the gum retraction itself is irrecoverable. I have been waiting for a doctor's appointment to have my teeth checked out for about 6 months now. I can't help but think that in the process of doing my dissertation, I have trashed my health, at least to an extent, and now I'm just waiting to get an assessment how badly. Moving on, I think that whatever I'm about to do next, it should be something that I feel like needs no nicotine for motivation.
