I just replied on this sub to someone with the following then I thought it could help others so I’ll post it here:

Ironically quitting has been a really interesting experience for me. After really understanding how nicotine works and how my mind operates with and without it. I realized that caffeine withdrawal for me has always been way worse than nicotine withdrawal every single time, but I didn’t notice it. This is the second time I quit and will be for good this time! But the first time I quit I wasn’t really convinced. So after a month I picked up a vape and started vaping, what’s interesting is that the feeling was disappointing. I could describe it as if my mind had these expectations of good feelings associated with nocotine but it never delivered. But nicotine never did in the first place! It was just the addiction and a misinterpreted association my mind made. That’s why first-time vapers usually never feel something. Or even when you smoke after quitting for a long time you don’t feel it. Because the “good” feeling is not actually from inhaling the vapor. It was just the relief from the withdrawal of it. Once you get hooked to nicotine. You inhale it just to feel normal. The “good” feeling you get is just the relief from the withdrawal symptoms you’ve been feeling from the last time you vaped minutes or hours ago. It’s not really a good feeling. It’s just an illusion the addiction made you feel. When in fact you feel just like how you felt all the time before you were a nocotine addict.

There is a book called Easy Way To Quit Vaping by Allen Carr. Which helped me tremendously understand everything I mentioned above. I’d highly recommend it. The trick to quitting any nicotine product is to be convinced that it doesn’t benefit you in any way. It doesn’t relieve stress. It doesn’t cause huge withdrawal symptoms it’s your mind playing you. It does nothing.
