SC even 1 ciggy a day less will make it easier for you in the long term, instead of cold turkey have a think how many cigarettes you have a day & aim to one less each week, so if you have 20 a day, aim for 19. There is no urgency or mandate you have signed you will quit, do it at your pace as and when you're ready.

Little things which helped me were; Attempt 1, I told everyone I was giving up, people seemed to smoke more around me, asked me to hold their cigarettes while they did something. Attempt 2, I told no one, each cigarette I smoked I consciously let the cigarette sit between my fingers and burn away, less drags, less smoke in my lungs, less nicotine. I picked places where I would only smoke, so I had to get up and go there. I bought a pen cigarette sized & shape, rolled it between my fingers where the cigarette normally sat, I also stuck it in my mouth and on occasion sucked or chewed it. (Remove the ink first). Attempt 3, told no one, bought a large necklace to wear round my neck, I fiddled with it when the anxiety hit me & also stuck it in my mouth. I cold turkeyed it that time. But my earlier attempts had set me up so I knew what would trigger me & what to avoid.

I completely understand your need to protect your sobriety, make a plan, spread it over the next 12 months, take it one day at a time. I was a 30 plus a day smoker, at 21 I sounded like an elderly person with emphysema, started smoking at 9 yrs. From 16 I graduated from pinched cigarettes to buying my own, by 18 the first thing I did on waking was light up, by the time I got to work I will have had 4 & 1 as soon as I arrived. On weekends going out I bought 5 packs of 25 on the Friday evening, Monday morning buying milk for work I bought another packet as I'd run out!
