What is it that keeps you hooked?
Drug takers believe that they get some sort of genuine pleasure or benefit from the drug. That it helps them enjoy life, handle stress, relax and socialise. For this reason they fear that even if they do succeed in quitting they will be miserable and feel deprived for the rest of their lives.
In addition to that fear, they also fear the downsides of drug addiction; the health worries, the stigma, the cost, the slavery and although they work hard not to think about them they remain like a huge dark cloud at the back of their mind.
These are the fears that keep them hooked.
The method removes your need and desire to take the drug and removes the fears that keep you hooked.
