Any cravings I had were pretty mild - the worst was after Thanksgiving dinner that year, which was just a couple weeks after I started vaping. But I made it through that and never really had a problem. I kept cigarettes handy for quite a while - I figured they were always going to be around to tempt me, so I may as well get used to it. And they were a security blanket - I never felt any panic about not having cigarettes, since they were right there if I wanted one. I just chose not to have any. There are still a couple of dusty old packs out in the garage.
I totally get that - the security blanket thing. The way I'm looking at this is that it's an experiment. If I want to keep smoking analogues, I'm no worse off than I am already. Best case scenario, I start vaping and stop smoking analogues completely. My expectation is that I'll do both for a while and then pick a favourite. Since I spend $100/week on cigarettes now (I buy loose tobacco and hand roll), spending that amount for a month long experiment with vaping is no big deal. I'm not going to beat myself up if it's not for me, but since I'm a tech guy and and a tinkerer, I do expect that if I can satisfy my nicotine addiction and also indulge in those activities it will be a success. Wish me luck!
