I quit about three years back. I'd been smoking two packs of Marlboro reds a day for about twenty years. Well, I was getting problems with my knees (fine when I was up and about, but hurt like hell when I stood up after sitting still for a couple of hours), and figured I was getting to that age where it was getting a bit long term - didn't we all reckon we'd be able to quit after a couple of years? Well, twenty years later... Anyway, years back I'd read the Allen Carr book (for UK readers, not the camp comedian, the other Allen Carr), and it stopped me even wanting a smoke for about a week. Then I was in a room full of smokers and suddenly couldn't understand what the attraction was (which was rather odd seeing as a few days earlier I'd been the heaviest smoker out of all of us). I ended up having a puff on a ciggy, hating it, but having another puff until I'd finished the damned cigarette and wanted another. Great move, huh? But I always remembered how that book had turned me, not into an ex-smoker (the one thing no smoker ever wants to turn into), but effectively it had turned me into someone who had never smoked. I didn't care if people smoked around me, I didn't crave it, I didn't resent it. It had simply, albeit briefly, not been on my radar. I always swore that, one day, I would read that book again, and not make the same mistake of following it up a week later with a crafty smoke. Fast forward ten years... I found that old book and read it again. I'll admit that, for a day or two, I was in a foul mood. I really didn't want a ciggy, but part of me was craving one. It was a battle between me and the addiction I'd been feeding for decades. I knew that, with every minute, I was closer to being off the fags, and that if I did "treat" myself to another smoke, I'd have to go through that all over again. Mrs Grabsplatter kept her head down, and excused my temper (thankfully). Anyway, after about three days, I was there. I didn't miss it, I didn't want it, and better still, I didn't think of it. Ever since then, I have effectively been a person who never smoked. There is no residual craving, or desire. When I see old photos of me with a cigarette, it takes me a minute to work out how this can be. Remembering me smoking is like remembering me with three hands - something I find hard, as I never had three hands. So, personally, I'd recommend trying that. There must be places to download a free version, and it doesn't nag. At no point does it say "this is it, your last one", or anything else similarly scary. Hell, if it works, you've stopped. If it doesn't, you've lost nothing. It is cheaper than a lifetime's supply of patches, or vape refills though. BTW, whatever the problem was with my knees, it stopped happening when I stopped smoking.
