Former Smokers ?

Do any former smokers (cigarettes) have advice on how you quit smoking !? I’m struggling over here 😩

I don’t want to take medication for it.. Chantix, Wellbutrin etc. I’ve read Chantix has horrible life long side effects.

I have to quit smoking for a surgery I need to get, so I can’t do the nicotine gum or patches either as I have to pass a nicotine test

I do have a vape that has 0 nicotine and I bought a cigarette flavor juice but it’s not doing much for me

Thank you in advance 💛
