I'm just over three weeks without an analog. I actually bummed one from a friend in a bar last weekend and could only smoke half, but that's been my only slip and I'm glad I did that now as I have no desire to switch back. But I can honestly say that my habit and daily routine of smoking have been broken. I no longer think of smoking on a daily basis, and i don't miss going outside to smoke and get "fresh" air. I'm now vaping less, I've moved down to 6 mg, and I don't have strong nic urges, not even after meals.
So now that I'm three weeks in without an analog (they say it takes 21-30 days to break a habit) I no longer feel myself thinking about smoking. I'm not even chain vaping now, just one or two vapes and that's it. So I'm really glad not only for my health, but I feel liberated in a sense. I feel free of the stench and thoughts of worrying when I can smoke again, and this makes me so glad I don't smoke now (aside from the negative health effects). The transition was never very hard, and it's been we'll worth it.
