Hi Randilynne,   To completely remove the craving which you are experiencing in your body, you must give it what it is yearning for. You must start using your lungs for what they were made for and their one and only purpose is to provide your blood with the oxygen, but its not that easy as your lungs have been drenched by the tar given off from your previous smoking. However if you now introduce your body with oxygen which it has not received in it's correct consistency, you will discover that the craving will completely disappear.   This will not happen overnight, but it will gradually fade which regular use. Start using your lungs and breathe deeply every time you get a craving for three to four minutes and whenever you can think about it do a breathing exercise and then you will gradually feel what the power of oxygen can do for you.   The best of luck.   Paul
