Hang in there. They say it is the worst of all drugs to come off.
I quit 21 years ago. Quit cold turkey with the help of prayer, and never looked back.
Perhaps some people are more addicted than others, and some just smoke as a nervous habit
I was a pack to a pack and a half smoker for about thirty years, and I have never had the urge to smoke since I quit. My sister quit smoking about ten years ago, and says she thinks about them to this day.
My wife still smokes, and if she runs out of smokes, she goes into orbit

You would think I would have saved money when I quit, but"NO" She doubled up on the damn things, and the Socialist Republic we now live in has quadrupled the cost of them. "Damn I hate Cig's"
