I've been down the same road buddy. You've got really a want to quit for it to stick. I started smoking when I was 12 and couldn't ever imagine not smoking, especially when drinking.
I was flying back from Las Vegas a few years ago with 2000 'fags' stashed in my stuff hoping I wouldn't get pulled by customs and thought WTF! Why am I doing this, I got home, sold the Malboros and haven't had one since,it was 6 years ago.
You do get a WTF moment dontcha? Mines was hiding out the back garden so my daughter wouldnt see me smoke and I thought jesus man Just quit! Well done on staying off them!
It was lucky as the very 1st e-ciggie had just come out so I had that as a crutch for a while to help break the habitual stuff. I'd be tapping my pockets when I got off the tube etc looking for something to do with my hands. It was hard when having a few jars, but you do break it.
Hardest was the doobies but just went back to the bong 😀
The payoff was the extra cash as I was 40 Malboros a day
