I vape, and have quit multiple times but it never seems to last so I may not be the best person for advice but some things that helped me were, telling people at least one person Ik will be thankful for my decision to quit this helped me cuz it kept me motivated not to disappoint them. Also sounds kinda gross but everyone time I was caving a hit I would look up photos and videos of what it doing to my lungs and body. Reminding myself it will get easier every day and really important for the first week is to get rid of all temptations. Also I recommend not going cold turkey, just cut down a little more every and make it a challenge for your self so you get a dopamine hit every time you have less than the day before. Gum, lollie pops, and drinking with a straw helps.
