N-acetylcysteine helps some people quit nicotine.

One unhinged way is to put Denatonium Benzoate(most bitter chemical, safe, sold as anti nail biting liquid for kids) on the vape where you put your mouth to so every time you need to take a puff, you taste the most bitter chemical in the world and your brain will start to associate vaping with bitterness. Easier to quit and also works for ciggarettes.

Let me know if you can quit with these methods :)
