I did not fit into any of the "typical" characteristics of an addict either. I came from a good home with 2 parents who gave me basically everything I needed. Neither of them were addicts nor anyone else in my immediate family. I went to college, got a good job, and did everything set out to accomplish.
Having said that I still drank daily for decades, and towards the end to the point that it was destroying all those good things I had built/worked hard for. Quitting was one of the most important decisions I've made in my life.
