Champix. Nothing else works for me. Will power certainly didn't work for me. In my expereince and opinion champix will work when it works, no timeframe. Just keep taking until you notice yourself smoking less and less and the need for a cig has become weaker. Then test if how long you can go without. When it is forever you are there. Keep taking the course beyond the quit point. Lastly - NEVER be tempted to pick another cigarette up again. There really is no point - NOT even socially. ITS OVER!
