Ahh gotcha. Yes alcohol and opium are tough to keep people away from. Chantix worked the first time and within just a day or two made smoking a cigarette completely devoid of any pleasure. Zero problems with dreams.
The biggest epiphany you get from quitting smoking is realizing that cigarettes aren't inherently pleasurable, smoking one just removes the symptoms from nicotine withdrawal in a way that other nicotine replacements can't. While everyone seems conceptually know this, it's surprisingly hard to really get it to sink into your own brain. Truly understanding/believing that combined to a round of Chantix took care of things for good.
