Nice work on 3 days! I'm not sure what success or challenges you faced after your post, but remember that you fought for yourself and your health, and that's worth celebrating no matter what.
I think I understand your desire to quit cold turkey. Or, at least, I've had similar impulses. I think it's partly a pride thing, to me. Like, I don't want to rely on help from anywhere else, because it can feel (inaccurately) like a dependency as bad as cigarettes. Personally, the best success I've had was when I used nicotine patches religiously. I followed the steps exactly as prescribed, and it worked. It was hard. I was miserable. But it worked. I made it work.
As far as work goes, so what if you're unproductive for a few days or weeks? You work so you can support yourself and live life, right? You work for life, you don't live for work. Quitting smoking supports life, too. You can get another job. You can't get another life.
Stay strong, or get strong again!
