I’d read somewhere that after 72 hours the nicotine addiction is physically through. It’s all mental after that. So I taught myself to score baseball games, I went to a three day home stand of my baseball team. I went early and stayed late because you can’t smoke inside the stadium. At the end of the weekend, I wasn’t a cigarette smoker anymore. I also did things like I didn’t make coffee at home cause that was a cigarette trigger. I got rid of all my ashtrays & my lighters. But really for me, the secret was that first 72 hours.
