I gave up 40 a day 18 months ago, I didn't find that those patches helped a bit!!
I found the first few weeks the easiest, the difficult part is when you become complacent and think you have successfully quit!! then you are tempted to "just have the one" or having a pint with mates.
I still have a strong urge for a fag, but I am fighting it, my Mother gave up 20 years ago, she also still craves a fag!!
Just don't drop your guard, not even for one cigarette!!!!
