By looking at felt's join date, I would think that a year and a half would be enough time to get used to a pv. For some of us the pv alone doesn't get the job done. That's why several of us here in the smokeless forum have turned to nasal snuff and swedish snus. Snus works like no pv can. The whole tobacco alkaloids are not in the nicotine liquids. They are in snus and snuff. I tried very hard to make it with the pv alone. If I hadn't found out about snus, I would be smoking a pack and a half a day right now. I still vape a little to take care of the physical end of things. vaping does have a place in my arsenal but snus and snuff are what get the job done.
