The problem with bad habits is most people can't manage the moderation part.
I quit Feb 5 2008. I took my first long car trip a few weeks ago 1400 miles not one cig did chew a lot of gum. I stayed with my MIL who smokes non stop in
her house (that was hard). I miss it once in a while but not daily I don't miss the smell.
I could never smoke in moderation. Depends on what your definition of moderation is.
The Chantix worked great for me but I only used it for a month.
