Have you tried nicotine replacement besides vaping? I found it extremely hard to quit cold turkey since its so close to smoking.

Gum helped me more than patches. I found that patches would peel off with certain movements and when I became sweaty. Plus with gum you're doing an action which releases nicotine. There's a bit of a routine other than peeling something off and sticking it on.

I dont know how long its been since I quit. It hasn't been a year yet and I stopped using the nicotine gum maybe a month or two months ago. I still get cravings when I watch TV shows where people are heavily smoking but now I manage it by chewing regular gum and I trick myself into calming down.
