When my Aunt (in law) quit after 40+ years of smoking (she actually rolled her own cigs as a teen during WWII) she had to NOT talk to family and friend on the phone for about a month. She said it was weird because the phone would ring, she’d sit on her chair to talk and automatically reach out for the ashtray/cigarettes/lighter (that had always been placed in that location). It was simply a trained response. Unfortunately, you can’t just stop driving. I am wondering if an E-Cig may help you. From what I have read, it looks like a cigarette, and you puff on it. It isn’t the same, of course, but you could still “smoke” something (or close) while driving.
I have those! Unfortunately, they are so heavy I have to use 3 fingers to hold them up!
I wish they’d come out with a lighter one, one I can hold like a cigarette.
