Allen Carr's Easy Way To Stop Smoking worked for my wife and me.
Much appreciated - this was super helpful. Not so much the method or the book, but just taking the time to watch some yootoobs. I'd forgotten how helpful immersing myself in yootoobs was in quitting sugars. Even just documenting my experience here is helpful, because it exposes the bullshit. And nicotine addiction brings with it a ton of bullshit.
