I smoked 40 ultralight cigarettes a day for 40 years. I started vaping in June. I never meant to stop smoking, just add a little variety. But with vaping, I found I was only smoking 2 cigarettes a day, so after a couple of weeks, I stopped altogether.
I found that 20mg was right for me. Whenever I felt ready, every month or 2, on a whim, I dropped 2-3mg. I won't allow myself to feel any pain or stress, because I know if I do, I will start smoking again, which I refuse to do. 6 months later, I'm down to 10mg and still very comfortable.
I have no intention of quitting vaping, but I intend to continue to drop the mgs in this manner. I don't know what will happen, but maybe, just maybe, I will be a free man someday. It could happen.
