I used to smoke when I was a teenager, and was on quite a few a day. Here's a tip from an old Irish friend of mine. He said that the urge for a cigarette peaks after about 20 seconds, so sip from a bottle of still water. A few minutes later you might need to repeat it, but somehow or other, it really does take the edge off needing the fix. After a week or so of doing this, the urge to smoke definitely drops, and within a month, you can ditch the water and be smoke-free. It worked for me, & to prove my point, I sat between two friends who were smoking, just 4 weeks after stopping - and was fine! So good luck.
