I was going through posts and found this one too!
It is funny because I was thinking about this the other day and thought about my dad.
My dad is an alcoholic, I can tell when he has had a bad day when I phone him because he is wasted and tries to hide it. He has been like this for as long as I can remember (maybe one of the reasons I am the way I am now).
I remember my dad didn't always take us to the park, or to soccer games but we did go to disney and 1-2 camping trips etc.
well I remember my mom saying years ago that one day in my dad's mid 20's he just stoped doing things, quit his baseball team, didn't hang out with friends etc. and that seems to be when all the drinking started. Well of course I didn't think much of it when my mom told me.
Then the other day it hit me (when I had the bad attack at my mother inlaws store) They were all drinking wine etc and they offered me some. I don't drink.
Maybe all this time my father has suffered from it just turns to drinking! Maybe we have paople drinking who have been drinking for so long because there was no help for them. I mean can you amagine being a man in the 60's 70's and providing for your family and your wife stays home with your 3 kids and you suffer from anxiety and you have to work to provide for the family. you don't know what is wrong with you because there is no info about it and you think you are going crazy so you drink or do drugs to help you stop from going crazy!
My dad told me when I finaly started coming around and admiting it to everyone, that maybe he does suffer from it too!
So maybe that will help you on your quest, maybe there are studies out there to tell weather there is a link between the 2 (which I am sure there is).
