one month since I finished my last pack! In the interest of transparency, I did smoke 6 cigs (last one 3 weeks ago). Just feel great overall. No smell, lighter chest, are the big plusses. I broke both my running records (endurance and speed). They are intangible but important. Not so good: gained 3 kg (6lb?), very bloated, dry skin and breakouts. But an important side-effect is drinking less. It's hard to quantify as it's generally been a month heavy with parties and social occasions, but def the drinks last longer, and easier not to crack open a bottle on week nights. I really feel this is a life-style change all around. So for newbies: keep going! I am the only one I know who vape, and the social side is still a bit awkward, but I never planned to give up, and I now feel I might actually be a not-smoking person (not no-smoking as I have no need to judge, and I leave it open to smoke if I really, really feel the urge).
