My advice to stop smoking is simply...get a grip. Be strong, understand you control your limbs that cause you to smoke. Get control of that and set your body up to deal with the adjustment. Make swaps in your routine so your aren't just removing the problem, but tackling the pattern that lead you to smoke.
Here's where you can get the Daily Greens supplement I mentioned, as always I praise Onnit and their products.
