I was a heavy smoker until Apr 3 of this year. At least a pack a day, often 2+. I had tried to kick using ecigs to help, but with leaky tanks, weak pen-style batteries, and tasteless juice/vapor, it never stuck. I found a Haus brand setup in a Walgreens in April and some tasty juice at a local vape shop (vanilla/caramel w/3mg of nicotine), and haven't looked back. 4 months, no cigs, still haunting all the same dives & hanging out with all the same smokers. Only other change I made was to cut WAY back on the drinking. Last month, I picked this lil guy up (50w Nugget w/Cleito tank). I figure with the limited battery life, I can start to ween myself off this habit, too. So far, so good.
