Most of us would have had the experience of being in two minds about something. It is like one part wants to do one thing while the other part wants to do something else. Most of the time we are able to resolve the conflict and get on with our lives. But at other times it can feel as if there is another part that runs our behaviour without our conscious control. For example some people make a decision to stop smoking, avoid chocolate, cut down on alcohol, stop using a drug, break up a relationship etc. and yet they are unable to do so. If it is their brain and their mind then why can’t they make the behavioural change? The medical model says that we are addicted to chemicals. It says that brain chemistry, neurotransmitters, receptor cells etc. are at the root of the problem. Yet the addiction model does not explain how some people are able to stop an addictive pattern without medical intervention while others struggle desperately for decades.
If the addiction model was correct then once someone had successfully withdrawn from an addictive substance then they should be free from the habit for the rest of their life. And yet it is not uncommon for stress to kick off the habit once again. Look at inner conflict from an NLP perspective. We start by having the client acknowledge that there is a part of them that wants to stop a behaviour and a part that wants them to continue.
