Cigarette addiction is even more perplexing for me. I've had nicotine addiction before in college, quit, got the headaches and nausea and all that but IMO having the flu is worse, I just rode it out then it was done. I don't understand what goes on for someone who say wants to quit cigarettes, is trying to quit, is aware of the health issues, but still makes the very conscious dozen plus decisions that have to take place in sequence to get that next pack of cigarettes. I think deep down there is a side of them that is maybe extremely depressed, and self loathing, and maybe wants them to fail to quit because that would satisfy their own internal working model of themselves being a failure, too weak to ever quit. Something that goes beyond any one vice and is a general phenomenon, but unfortunately might never be appreciated with so many targeted vice-specific efforts vs understanding the wider whole.
