How is it working for you? Depending on how much you smoked, 6mg might not be enough. Its good that you are stopping cigs after 5 yrs. though. You most likely havent damaged your lungs irreversibly. When i was at my 5 yr mark, i had no desire whatsoever to quit. And that mindset only gets stronger over the years until you reach a point that you want to quit but just dont see it happening. Good for you for stopping this early. If 6mg works for you and keeps you off cigs, keep at it. If its not working so much, increase your nic content. But youve made the first step, dont look back. Vape on! And welcome to the forum. Youll find lots of info and really decent people here.
