Placebo needed

I am chemically no longer addicted, but the habit part is killing me. I smoked for over 40 years.

Anyone found a tool that you can mimic taking a drag? I have a wood dowel that I have used, bought a necklace that was supposed to mimic it. They help, but are not close to my 40 year habit. I think maybe I should buy a pack and use the cigarette as a placebo. But am afraid I will start again.

I don’t care if I have to use a placebo the rest of my life, I can’t smoke anymore.
