It’s great you’ve made up this decision! It’s not easy at all… if you have a friend you could do it with or join a support group it could help. Also, there are nicotine supplements that some find helpful and medications as well

I quit smoking after 12 years of smoking (since the age 14). One day I just decided I won’t do it anymore, I tossed my last cigarette and never smoked again. I guess because my partner doesn't smoke it was easier for me. Maybe you can quit together with your partner?

This is a method that lots of people look down on, but hear me out! It works! If you start chewing cinnamon gum regularly, then every time you try to smoke it will hurt your mouth. If you feel it's unethical then that's fine, but it is effective. I have a friend who did this last year and it was like the easiest cold-turkey quit I've ever seen.
