Like many folks here, I agree that there's a "turning point" moment when you feel there's no way you're going back to analogs. You don't want to judge others, but for me it's when I looked out from my office window at one of my colleagues, standing under a tree, in the rain, trying to light his cig, desperate for a drag. Meanwhile, I'm in my office typing away at e-mails, vaping happily and dry. Or, the fact that my wife hugs me randomly and kisses me with a smile because I don't stink. Or, when I hold my newborn and feel not an ounce of guilt that she's on my chest, because there's no tar/carcinogen that can hurt her. You know - that's probably what the "turning point" is - a sense of victory over the guilt that was smoking analogs.
... being a bit smug at not having to light a cig in a thunderstorm, under a tree, doesn't hurt, either
Congrats, and enjoy your victory with a vape!
