My not so deep thoughts on this:
I use my car every day and don't know how it works.  I just turn the key and drive away.  I know very little about how the car works but because I know how to drive I can use my car to reach my destination.  I don't give a thought about the inner workings of a car as long as it is working.
I use my computer everyday and I do not know how it works.  I turn it on, press a few keys and do what I need to do. (most times 

 )  I know NOTHING about how a computer works but because I know how to press a few keys in the right order I can use my computer to reach my goals.  I don't give a thought on the inner workings of  a computer as long as it is working.
I use  my NAL every time I am going to drink at least an hour before I drink and I don't know why it works.   I just take my pill and hour before drinking. I know very little about NAL other than what is discussed in book and forum but I do know how to take a pill an hour before I drink so that I can reach my goal of control over AL.  I don't give a thought about science, psychological or philosophical reasons it works as long as it is working!
Maybe if I was not seeing results I would feel more inclined to engage in the deep discussions - I am just happy it is working and giving me some hope that I can finally get control on my long time problem of alcoholism.
