Very similar here. Smoking buddy at work was turning 40 and was like “If we don’t quit now, we never will!” so headed to a random vape shop. Bought a vape for lke £50, was on 1.2mg nicotine strength. First day was fine. 2nd day was tough. 3rd was also tough. 4th day I realised “oh shit, never going back to smoking…I feel fine. I can work with this.” So that caused me to panick but then thought ok, bought the same vape as a redundancy (so as to not have to fall back on ciagarettes).
Then, after 6 months switched to 0.6mg nicotine. 6 months after that, 0.3mg. 3 months after that 0.2mg (put my high school chemistry hat on, figured 10ml 0.3mg + 10ml 0.3mg + 10ml 0.0mg mixed up in a 30ml bottle = 0.2mg per 10ml). 1 month after that 0.1mg, 1 month after that 0.0mg - 1 month later, stopped entirely (you genuinely just start forgetting about it, it’s weird).
Went from 30 cigarettes a day to no nicotine and no vape in 18 months.
