How did you stop smoking?

Hi I'm 34f. I have been a smoker since 22. I am so passionate about skincare for me it's self care . I hate that I am a cigarette smoker, it's honestly my only vice . I don't drink alcohol (never ever!), and try to keep my sugar intake to a minimum .

I tried Allan carrs book a few years ago and it worked however I relpased after 3 months , and I read the book again it just didn't work the second or third time .

Does anyone have any advice on how to stop/get rid of this awful habit I have 😭
