what they do is temporarily satisfy your addiction to nicotine.
You are the one who keeps yourself from smoking. You are the one who has control of your hands, not the NRT.
If you are using a piece of gum everytime a mental connection drives the urge to smoke, you may likely be ingesting much more nicotine than what you ever got from smoking.
If you start doing that you are setting yourself up for a lifetime of NRT addiction by believing that is what is keeping you from smoking.
They will help if you don't believe they are all that's between you and a cigarette.
It doesn't help to become even more addicted to nicotine by overdoing it.
Keep Them Away From Your Face with your hands.
