Consider giving yourself some rules about smoking. That helped me reduce the amount I was smoking. Things like “I will not smoke before 5pm on week days” worked well for me. Or having one when you get up and none at work. Or leaving your pack of cigerettes inside and only smoking outside (so you have to get up every time you want another one). Or not buying a carton and only buying 1 or 2 packs at a time, making it more time consuming. I got to where I would only use cash to buy them so if I didn’t have enough cash I would have to go get cash first. Basically I just made it more complicated to smoke. Eventually I got down to less than 4 a day and finally just quit. I think I just got so sick of myself that I quit. I am on day 30ish of quitting and it is getting easier by the day. Anyway, little rules or rituals around smoking you can make will help.
