Quitting smoking: Champix?

Quitting smoking is hard. I only ever manage to do it when recovering from an illness (cold, flu, virus, etc.), and then by not starting again. Longest I've done it for has been a couple of months, but I will try to persevere this time.

Nicotine patches/gum never worked for me.

Still going strong: coming up to 4 months with no smokes (cold turkey after a bout of swine flu). Not sure why this time I succeeded where previously I have failed. Maybe I just finally grew up...?
