I think there is a connection, at least with me. As I reflect on my life, I can see the trail.
I have always been uncomfortable in large groups - and I come from a large family - alcoholic family to boot! The first time I ever drank, I got squashed. I remember the original wonderful feeling of being a part of everything, finally, and then I was totally drunk.
That pattern continued. I also used "speed" in my early twenties - which actually help me drink more without getting drunk.
As an adult, same problem. It is not how often I drink, it is how much I drink when I do. It seems that the problem happens when I am in a group - I get lost somewhere, but I think I am actually overstimulated - but at the same time, I finally feel a part of the party!
I just came to this understanding in the last few days, so I am not exactly sure how I will use it. I also came to understand the "innie" thing as well. So I have a lot to think about...
I have a super bowl party to go to this Sunday - it should be interesting. At the very least, I plan to observe my feelings and reactions with my new found knowledge - and I plan to not drink to diminish my anxiety.
Wish me luck and lots of information.
PS - In retrospect, I think my father was an Innie and that was the root of his alcoholism. He wanted so terribly to succeed, and to do so he had to push himself into the world - being an Innie - he used alcohol. In addition, misunderstanding himself, he wanted a large family - he had 5 kids. That is enough to send an innie running screaming from the room!
