Lost my best friend from high school to it 5 years ago. I'd be interested in catching this documentary online to see if any of his friends are in it. I knew quite a few people that were in that life.
As far as myself, I very much echo Derek's "zombie" sentiment. I got my tonsils out a few years ago, and as an adult it's a much bigger deal than when you're a kid. I missed 2 weeks of work and lost 20 lbs because I couldn't eat. They put me on liquid codene and by the end of the 1st week I couldn't sleep without taking the shit, and if I didn't take it I got really bad headaches and sick to my stomach. It was miserable. If that happened to me after just a week, I sure hope I don't ever get into a situation where I need to be prescribed something like oxy.
