When I have the time, I like to do a Saturday series. This one, my favorite teachers, is a true labor of love. They each have expanded my world. I begin with Marc Lewis (bio) whose blog, Understanding Addiction, continues to challenge and intrigue me. His book, Memoirs of an Addicted Brain, was the first book to combine science and memoir. He has both lived it and studied it–addiction. Prepare to find a true leader.
