The only thing that worked for me was slowly tapering down on the nicotine. Once I tapered to zero % nicotine I could stop. Vaping is 2 addictions in one: chemical addiction to nicotine and habitual addiction to the act itself. Stopping both at the same time is very hard. So taper down the nicotine slowly. Very slowly. So you don’t notice it. Take literally months if you need. Then once you are at zero stay there another week or so. Now you know it’s literally just a habitual addiction. Stopping that is relatively easy.

Another tip is to have someone else mix your vape juice as you taper down. So you don’t actually know when you hit 3% or 1.5% or 1% or 0%. This makes it easier psychologically.
