If the "7 days to break a habit" thing was 100% true there would be a lot more nonsmokers out there.

I believe God supports those who are already doing the heavy lifting.

E cigarettes are great because now people aren't stinking up public places, but it is still nicotine, it isn't healthy for lungs, and it is still an addiction.

What helped me quit most of all was joining a quit smoking online community for support, but after a couple of months one has to learn to be more self reliant.
