Hello Tadpoles. Welcome to the forum.
vaping made me cough at first. We all are different, but it took me a full day to figure out the inhale, as compared to the cigarette inhalation.
Many of us succeeded in quitting cigarettes through a period of dual use, continuing to smoke while experimenting with vape flavors, equipment, nic strength, pg/vg ratios, the element of "throat hit".
I don't have all the answers that will apply specifically to you. I can only encourage you to keep at it until you get the vape that is right for you, so satisfying that one day you say "I like
vaping better, so I'm gonna quit cigarettes". For me, it was about six weeks of continuing cigarettes while experimenting with
vaping, but once I decided to take the leap, I quit the cigarettes in one day.
Keep in mind, you're the boss of you.
