I'm a newcomer, but if you don't mind, I'd like to offer a few words of advice.
First off, if you're prone to anxiety, then you need to stop stressing yourself out by visiting web sites and reading materials that are intended to scare you. Smoking's bad for you; you know that, so move on.
Secondly, stop treating vaping like some sort of pass or fail proposition. Remember that most people who switched to vaping quickly did so because they hit a sweet spot with flavor, nicotine level, etc., and wound up enjoying it just as much, if not more, than smoking. Instead of getting upset, explore a bit and do some experimenting.
Thirdly, be kind to yourself. Keep your view positive. You're doing something enjoyable that is helping you move away from a habit that is harmful. Why do you want to quit smoking? Because your scared? You feel like something's wrong with you? Focus more on how you are improving yourself, rather than trying to wrench yourself away from a habit that's notoriously difficult to break. I absolutely refuse to suffer, and I know how I react to "quitting" - it's not pretty, and it always fails.
Fourth, set reasonable goals. A million years ago in a land far away, I read an article that said if you can keep your cigarette intake below six a day, it's almost harmless. I wish I could find a link to that article, but it was pre-internet, and I have no idea if that idea's been debunked since I read it. However, six is a nice, round number, so once I felt comfy with the idea of replacing cigarettes with vaping, I set an allowance of six cigarettes a day for myself. However, instead of focusing on that, I made it my mission to find the juice flavor & strength I like. I haven't hit my daily allowance for a week; in fact, I've only had one today, and feel no cravings. Why? Because I'm vaping a tasty French Vanilla 18mg juice, and I take a hit whenever I want.
I refuse to treat that one cigarette I had with my coffee this morning as a failure. It isn't. I used to smoke at least a pack a day. Having six or less cigarettes in one day without chasing my husband with a cleaver, beating my kids or kicking the dogs is nothing short of miraculous for me, so I've been high-fiving myself like I just won a silver medal.
If the day comes when I go an entire day without an analog, I will go on this forum and crow! And I know that these good folks will cheer me on. They're wonderful like that.
Anyway, that's my long-winded opinion, and it's worth what you paid for it.
Have a foggy day!
