It took me 10 years of off-and-on quitting smoking to actually kick it. Lately, I've been doing well. Not leaving my home because of Covid has seemingly put it down for now, but a bad day and a stress urge could undo everything. And I didn't ever smoke that long or that heavily. Just try not to smoke cigarettes, it won't make you cooler, and you'll actually miss out on a lot of time with people. Especially when your friends don't smoke so you gotta step away every couple hours to smoke a cigarette, taking time to work back into whatever is going on when you return.
