Time to stop the “casual smoking”

I was never really a smoker. Some time after quitting booze (over 2 years ago) I thought it might be something to do to boost a bit. But I sense similar patterns as with my alcoholism, all secretive, feeling bad, stupid and why smoke when I could easily quit. Moreover being an anxious person by nature, which was indeed greatly reduced by removing alcohol, smoking triggers anxiety after one cigarette, physically by heart beating faster and other symptoms and mentally, guilt, fear of being caught. I don’t know how many packs I buy and throw away after two cigarettes saying this is the last. Same with coffee which gives my sensitive nervous system similar effects; speedy, over alert, impatient, unfocused, easily distracted. And yet I have the solution right there. Have tested it enough to know it’s not good for me (or anyone) or my wallet and yet there is a habit that kicks in - like I need to do a daily clinical test of that tea, that didn’t help. Insanity really. Not really looking for advice but if anyone is in the same situation (falsely believing it’s relieving stress) on really making that the last one. Have a good day all.
