I am not sure the stuff is active or not..I am trying hard to quit smoking and followed many ways without much success..
Best advice I can share is an explanation of how nicotine and caffeine interact. They cancel each other out in your blood stream. End result, smokers usually drink a lot more caffeine products than non-smokers. More cups of coffee, or soda, tea, whatever. It's just less effective when you smoke. It's also why so many of us love a cigarette with an after dinner cup of coffee.
When you quit smoking, you usually stick to your normal caffeine habits. This means you are jittery and shaky and really really really craving a smoke. It's not nicotine withdrawl. It's caffeine overdose. Your body intuitively knows that the cigarette will fix the issue.
I need to work on the long term problem (staying off of cigarettes), but I can usually quit for a year or two at a time before my wife starts smoking again and I fall off the wagon with the following approach:
Quit Day -14: Two weeks before you plan to quit smoking, stop drinking caffeine. All of it. No coffee, no soda, just switch to water. If you can do this 30 days ahead of time, it's even better.
Quit Day -7: A week before you plan to quit, switch to American Spirits. Doesn't matter what strength, but lighter is probably better (Yellow Box). They aren't healthy, but the also have zero additives. You will feel like garbage the first couple of days as your body gets over the addictions to all the additives in regular cigarettes. However, since you're still getting nicotine, your brain doesn't connect the two. You just feel sick and your brain doesn't know why.
Quit Day: This one isn't going to be as bad as you'd think. You'll be pretty surprised at how easy it is to override a craving. Avoid using food as a substitute.
Quit Day+1: Less fun day, but same advice as Day 1.
Quit Day+2: This one sucks. The worst day of quitting, period.
Quit Day+3-5: Surprisingly easy. Not much trouble at all unless hanging out with a smoker.
Quit Day+6: This one ranks just below QD+2.
There is another few milesones. 12-14 days after you usually have another highly stressful 'Must smoke!' day. Then it's 3 months, 6 months and a year. After that you'll have days where you want to smoke on occasion or days where you walk outside and find yourself reaching for your pack. That's going to likely be with you forever.
Hanging out with / kissing smokers? Not a good call for long term successfully staying on the non-smoker wagon. In the last twenty years, I've smoked for about 13 of them been off for 7. Gone as long as 3.5 years without smoking. Every time it's my wife deciding she can't stand not smoking any more that drags me back in.
