Getting all upset about it is one way to NOT get it done. Stress will just make you want to smoke more. If you try to gradually replace this cigarette, then the next cigarette, then the one after that, with vaping, it gets a lot easier. Make it a competition with your self: tally every cigarette you smoke in a day, then the next day, try to smoke fewer, or at least, not more. that way it's fun and challenging, not stressful and impossible. Quitting "cold turkey" really isn't necessary. If you do the gradual replacement thing, then for the times when you REALLY NEED a real cigarette, go have it! Enjoy the hell out of it! Stop beating yourself up because you're addicted to something that very few of us could have gotten free of, without vaping.
I'd agree with what's been said regarding PG/VG, and also... you're inhaling SMOKE when you smoke... you gonna let a little VAPOR hold you back? (it's all in your head! It's your brain fighting tooth and nail to try and keep what it knows!)
Also, keep this in mind: Vaping is not really meant for smoking-cessation. It works better than anything else available, but considering how useless all that pharma shit is, that's not saying much, is it? Vaping is beneficial because once you do quit, you have a replacement for the smoking, so it helps you STAY quit -- but making the quit, that's still on you, completely down to your own determination and commitment to making it happen. It's not a magic wand, just a good replacement for smoking when the urge comes upon you. But you have to make the commitment and STICK TO IT.
Once you have actually quit, if you find that the cravings just will not stop, there's an answer for that, called Whole Tobacco Alkaloids. WTA is useless for actually making the quit; you have to do that part yourself. But WTA will completely eliminate physical cravings, once the cigarettes are completely gone.
