It took me a good 2-4 weeks before my cravings started really cooling off. It was hard for me to be around people smoking or to be able to turn down smoking when I drank, and that honestly waxed and waned for 6 months or so. Now that I'm on the other side of it I am sooooo happy to be done with it. It's so worth it, I promise. Check out Easy Way to Quit Smoking by Allen Carr. Reading that book when I was ready to quit really put things in perspective and strengthened my resolve in a big way. I think you can find a pdf of it for free.
