I hear you! Congratulations on the switch, though. I can't believe I've been smoke free for 5 months and I haven't missed cigarettes at allfor about four of them!
My biggest hurdles, initially, were the "trigger situations". And driving on the highway, lol... two days after I got my KGO, I had a 6 hour drive, and it was brutal. I was very lucky to have the KGO by then, as the previous setup wouldn't have cut it!
I'll just re-post this here, now:
Apart from the chemical "addiction" there are a lot of psychological / situational triggers. For me, for instance, such would be finishing a meal, having a dead time at work, finishing a TV show episode, driving, etc. You need to identify yours and make sure you have you PV ready and start vaping as soon as the triggering event happens, preferably before the craving hits. You won't be able to avoid all cravings, but this could help.
I was lucky enough to be able to switch over without a "transition" period, but many users say they had longer time of vaping and still lighting up here and there. It is important to not look at those cigarettes as failures, and keep vaping trying to maintain the vape as your main fix.
Whenever you can, do not stop vaping until you are satisfied. Nicotine is absorbed more slowly from vapor, and you may need longer "sessions".
Find your nicotine concentration need (the miligrams listed), and don't try to taper it off too quickly.
There's a saying around here, I don't know who coined it, "trust the vape". It will help you with the cravings, you just need to keep doing it. Don't give it up - there are many ways to increase the "kick". Depending on your setup, but you may need a midsize or large battery device, or play with the resistance of the cartomizer / atomizer. Maybe consider variable voltage, or a 5-6V mod or passthru.
It's vital that you explore the flavors to figure out what you can vape with pleasure for longer times. You may want to use such an "all day vape" at lower nicotine strength, and have a "rescue vape" with higher nicotine for particularly bad cravings.
