People who have never smoked have no idea what an accomplishment this is. Breaking that smoking cycle is one of the hardest things I ever did. It took me 3 or 4 cessation attempts before I was done for good.
I too grew up in a smoking household. My mother chain-smoked up until a year before her death. She had chronic respiratory ailments but just couldn't give it up until admitted to an Alzheimer's lockdown facility. That's certainly no way to stop smoking!
I've been clean for over 35 years. After several years of quitting, the tightness in my chest while exercising disappeared, stamina improved and I was actually able to taste what I was eating. Plus, the odor of nicotine is dreadful once you stop. While I smoked, I never noticed it. Just the people around me noticed, particularly the kids.
So congrats on a very wise decision! Your health will thank you.
PS: It took over 10 years for my 'urges' to go away. Every once in a while, I would 'sneak' one or ask for a drag off my sister or a friend. Every time I did that I was ultimately sorry bc it never tasted as good as I remembered. If fact, the taste was awful. And then, even the urges disappeared. For that, I'm eternally grateful.
