While I STRONGLY encourage self belief and positivity as the MINDSET in quitting smoking or any other endeavor, I found that a "lung cleanse" which is not as scary as it sounds , worked for me. Good anti-oxidants like ginger and turmeric, with onion, boiled and taken with honey seemed to curb my need to smoke.Perhaps just a warm glass of milk, with ginger, turmeric, a dash of pepper to activate the curcumin in the turmeric, same cinnamon and sweetened to taste might as well be the trick. I take that now for calcium and health benefits.
I found an article which may proved useful to some. It surely inspires good health at any rate.
