If I was blessed with average or above average social skills I wouldn't have needed Alcohol in order to socialize. Alcohol was a confidence builder that I needed to face the rest of the world. When Alcohol stopped working I withdrew from society because I felt that I didn't belong.
I seriously doubt that there's many Alcoholics that are of the Social Butterfly caliber when they're not drinking. Mainly becaues high self esteem isn't an asset that many Alcoholics have.
