I could never smoke when I got upper respiratory infections (colds, flu etc). Wouldn't even want to until the illness passed. So I figured I'd wait until I became ill; pretty much every winter I get a cold or something.

I got a case of sinusitis. As usual, I couldn't/didn't want to smoke. So no smoking and no withdrawal symptoms at all for the first week.

Once the first week was out of the way, it became 10 days with no nicotine, then two weeks, then a month and now 5 weeks, with the cravings all but gone.

Probably not the most usual way to quit, but I had tried probably a dozen times using nicotine gum, patches and sprays, and it was always hell.
