I quit the day I got my 510 and that was on September 5th, 2009. Getting a PT for the car and home has only made it that much easier to never even think about lighting up again. Just ordered my first eGo. So excited!!
I think the OP was asking about quitting smoking AND vaping: quitting all of it. Anyone plan to do that?
(FWIW: I don't, but I think it's doable. I suspect it'd be easier to quit vaping than smoking)
