I, too, drank to improve my sociability. I drank more, and more and more in order to reach that place of comfort. It got to the point that people marvelled at how much I could consume and stay relatively unimpaired (or so they thought).
Alcoholism is a serious disease and harms so many functions in your body. I didn't think I had a problem. I didn't get massive hangovers, or get violent or anything. However, I was wrong.
When I decided to quit, when I admitted that there might be a problem, I played that game....I could manage my drinking. I tried that for a year before I realized it wasn't working. Furthermore, once I admitted I had a problem, I couldn't enjoy it anymore.
I've been clean and sober for over two years now...I may not have that so-called 'ease' of socializing that I believed I had, but I'm SO much better off in all other areas.
Take it easy...
