Quitting smoking: Champix?

i've literally just accidentally quit smoking, I think?
i went out to this party on friday and smoked like a fish
terrible hangover the next morning, couldn't even think of injecting myself with more toxins...
and so on, and now it's been about a week and i feel fine (bar a tiny moment of panic last night when i had a pint)...

moral of the story, get fucking blasted and see if that helps.

Thats how I ended up stopping. I tend to find its the first day or two thats really bad, and after that a psychological barrier has been got over. Had a heavy weekend which lead to me coming down with the lurgy and didn't leave bed for a day or two, or the hosue to get tobacco for a week..
