I'm 8 days without a cigarette and very little nicotine replacement. Yesterday I had one 4 mg piece of nicotine gum that I chewed on and off throughout the day and that was it. I'm just hoping that these cravings get to be less often and less powerful because I don't know how much longer I can continue to fight them. If anybody can share their experience and how long Cravings Last . Also when they start going away.
