Giving up addictive drugs is not easy. The more a moving train accelerates, the more difficult it is to get off. Ratcheting up the difficulty by taking more of the addictive substance into your body will create more need.
Need is the mother of desire. Study a bit of Buddahism and you soon learn that desire is the source of all suffering. For the addict, this appears all too evident.
It follows that to reduce your "need" you need to reduce your intake. The same applies to smoking cigarettes, possibly one of the hardest habit of all to give up.
Joe smoked tobacco for twenty years and tried to give up on numerous occassions. He hated smoking it, but somethng made it impossible to stop, until his health started failing. Then he smoked his last cig and has not touched tobacco since 1998. We asked Joe what his secret was, was it nicotine patches? No.
Joe said that it was the numerous times that he had rehearsed giving up, each time he said to himself, hey - its okay - you are going to start again in two weeks - and with that he was able to cut out the fags for two weeks. Each time he restarted, he did so with an intention of repeating this promise to himself in a few days. And he did. After a few months of starting and stopping, Joe felt it was easy to just stop forever.
The same principle is at work as used by nicotine patches, reduce the amount of the narcotic in the system, until the body becomes used to not having it present.
The same principle should not be applied to depressant drugs, like herion or alcohol. With these a strict reigime of drying the drug from the body is necessary and then staying clear of the addictive substance for ever. One small drink can lead the alcoholic back to full fledged addiction.
Why? Drugs that tend to stimulate like nicotine or THC give the user an inflated idea about themselves, whilst they are under the effect of the drug. When they come down, the need is created in a state of relative weakness.
Conversely with drugs that depress, the weak state is when under the influence. Therefore it follows that to break the habit, maintain the stronger state.
