"[Zevon girlfriend] Annette Aguilar Ramos: Warren didn't preach twelve steps, but held the principles in the highest integrity. So, when he found out that his sponsor was shooting heroin, it was a major devastation. When he confronted him, his sponsor admitted using, and that really disillusioned Warren. The idea that the principles are divine, but people are fallible, was the lesson, but it created a distrust in him for people. Then, when it turned out that his manager was doing drugs as well, it was too much. He stopped going to AA meetings right after we broke up. After that, our little bad boy became a real bad boy. I kept trying to regain what we had had in the beginning our relationship -- that monogamous, committed relationship. But, Warren had tasted the other side and liked it."
