"It was just a matter of time before I got caught and my business ended up on the cover of a tabloid or I went to jail or, worse, I ended up dead. When I look back on it now, I don't know how I didn't end up in a body bag. Eventually, I got so sick and tired of this charade. No one who was in my circle, who knew me as Mike, was allowing me to get high." "I had to slip away to do drugs. I had to hide it. I'd be gone for days at a time.
