Yeah, don't sweat it. We are all (or I would think so) addicted to nicotine, so it's not an easy thing. And we all have to admit that while vaping is REALLY close to smoking, at the same time it's completely different. We've spent so much time in our lives smoking that sometimes it seems like the only thing that will scratch that itch. You already pointed out the fact that you spent two months NOT smoking, so try and focus on that.
