I think that one of the difficulties with the 'reptilian brain' versus 'higher brain' stuff, is that it is very, very hard for our logical rational brains to overcome the strength of the craving in the moment (note the "I want a baby, and I want it NOW" comparison).
And to be honest, that is what a lot of us are struggling with on a day to day basis. I think I will print out the article, and in particular the list of reasons and their link to emotions. I think it will help my rational mind to understand what the underlying problem of the 'little voice' is likely to be.
However, what the article describes well is 2 functions of the reptilian brain - dealing with 'lack' of something (food, sheleter, anything that makes us feel good) and dealing with 'attack' (anything that threatens our safety NB this is why we still do things that are inherently dangerous because these 2 funtions in out reptilian brain are in competition). The reptilian brain has a third function, which is often ignored, and that is the ability to self-soothe: to feel compassion for ourselves, to accept things just as they are at this very moment.
Our higher brain, with all its cleverness can remember thngs that happened in the past (and feel shame / guilt etc) and it can also imagine things that might or might not happen in the future - and use those memories and inticipation to help us moderate our behaviour.
People who practice mindfulness meditation do not focus on the higher brain, which can fight and struggle against the base emotions of the reptilian brain, but instead they develop the 3rd function of the reptilian brain - acceptance and self love.
For me personally, that is why meditation (particularly some of the buddhist traditions) can help me a lot - it takes away the struggle and the battle, which makes all the 'trying to stop drinking' so terribly tiring, and it allows me just to rest in what is going on now.
In the summer time I was walking with a bloke who is a buddhist and we passed a field of horses. There was a mare eating the grass and one of the young male horses was getting all frisky and trying (unsuccesfully) to mount her. The stallion came along and for a moment there was tension, aggression, erect horse penises, snorting and stamping. The young horse backed off and literally 30 seconds later all 3 horses were munching the grass peacefully. The bloke I was with described that as a perfect example of mindfulness and meditation - not getting into some 'enlightened' state, but being able to settle into the 3rd function of the limbic brain - not remebering the 'lack' of sex, not focusing on the 'attack' and not replaying the scene or imagining what we might have done differently, or how we would deal with it the next time. The third function of the reptilian brain allows us just to enjoy the subtle pleasures of the moment - sweet juicy grass, the sunshine and fresh air.
Tne more I can develop my ability to 'be in the moment' the less pain I feel from the inevitable times of lack and attack, and the less I have to struggle with remembering and imaginings about alcohol.
