I've found that you have to reeeeeeeeeeeeeeeeeeeeeeally want to quit more than anything. No bullshit 'i'll just have one more' or switching to menthols/rollies. That didn't work for me, I smoke a pouch of golden virginia a day with menthol filters now! Patches did work for me, but you still have to have a bit of willpower of course. Always have something to keep your hands busy aswell, I don't know about anybody else, but its the process you miss as much as the nicotine when you do stop - the whole pulling em out of your pocket, getting one out the pack/rolling one, lighting it, flicking it/putting it in the ashtray etc. Avoid drinking aswell! I hear those Nicorette inhaler thingys are quite good too:)
