I can say that, as of yesterday I am 30 days without smoking. The headache, shakes, chills, restlessness, and anxiety will go away. Breathing, smells, taste, will return with full force. You will start to notice that your triggers will push you to you PV instead of a smoke.
Not sure about everyone else but I now feel a sense of pride when I am around smokers and I pull out my Ego. You will answer many questions and share with others and you learn more. I know that while it may not be the best, it is a hell of a lot better than what I was doing before.
Keep it up and you will not regret it.
