Nasty little habit

I have a nasty lil habit of 🚬. I've been smoking since i was 18 and I've tried to quit so many times. My husband dealt with it for 2 years and told me to stop. I tried but everytime i got to the fillin-station i get a pack of 🚬 and its not like i mean to it just rolls off my 😝. Ik some smokers who have went cold turkey but everytime something gets under my skin I'm looking for a square so I dnt have to make a scene. I do wanna ✋ but it's hard and ik its bad esp when ttc. Any advice would be helpful.
