Is FreshStart™ a permanent solution?
Yes. With this method you will become a permanent non-smoker.
Non-smokers do not need to fight any urge to smoke, neither do they want to smoke because smoking is no longer a part of them. Smoking will no longer be a part of you.
Of course it is possible for you to deliberately sabotage your own achievement by willfully smoking in order to "prove" that this method did not work. However if you really are committed to quitting, you would dismiss such a self destructive idea.
