Do you drink coffee? Sodas? Caffeine has similar effects on your body that nicotine does. Both are addictive, however I do think whatever you're reading is over blowing the effects of nicotine. This is what some want you to believe and they're perfectly willing to hype up the negatives without looking at the entire picture.
I clealy didn't mean to discuss the health aspect here.
I just want to keep blood pressure levels/heart rate lower throught the day because it's very important for longevity and that's a fact.
Coffee in the morning is bad in terms of elevated blood pressure, still it's off my system by noon. Rest of the day I would like to keep my blood pressure in check.
It was proven multiple times in studies (that I of course won't even bother to look up, sorry) that nicotine wrecks your sleep (increased resting heart rate) and has negative impact on GYM performance (bad bloodflow) - these are really primary things I would like to fix with setting puff limits in certain times of the day other than just keeping the levels as low as possible throught the day.
Discipline seems to be important here indeed,
Discipline is easily wrecked by different life factors and actually even because of bad sleep. Sleep is wrecked by nicotine - there's negative feedback loop

Anyway, life puts us through different hardships and next time you know you're mindlessly sucking that thing again 24/7. Especially if work/lifestyle allows it.
I was just hoping to find a decent solution like I once found on mobile phones for Tiktok kind of habbits. All you need is a signal “No, you’re abusing this thing. Wait some time and try again…”.
