Similar to what Solo described I had a very real problem focusing my mind and concentrating.
I would have a hundred different thoughts all at the same time.
Because my thoughts were constantly "racing" I had difficulty reading a book,following a conversation or even making a simple decision about where to go for lunch.I also tended to be very forgetful.
I would have three or four different tasks going on at the same time and not be able to properly complete even one of them.
As I mentioned alcohol was one of the few things that would help to "quiet my mind" so I could sleep.
However alcohol was a double edged sword that only helped in perpetuating and compounding the problem
It is a very uncomfortable place this state of "restlessness and unease",but AA helped me to develop an understanding of myself and my condition.
Working The Steps and developing a relationship with my Higher Power was able to instill in me a sense of calmness and peace that I had not known in a long time.
