Welcome, Halix. I'm also a 30+ year smoker who just walked away from the habit after my first vape on serious gear. I'm 4 weeks in and still just stupefied at how easily I was able to turn my back on the nails after failing so many times with other methods.
I had given up trying to give up (much to my wife's relief, I'm told I'm even more of a jerk when I can't get my fix) a decade ago. With vaping, it's a whole new day, every day.
