Alcohol worked for me for the same reasons you have outlined in your post -- until it stopped working and started taking things away. My world got really small, in fact, it was just me and a bottle. The Steps of AA, commitment, dedication, and a boat load of changes have completely changed my world. I no longer need the crutch of alcohol to deal with life's problems.
