We've had similar experiences, although it was oxycodone that had its grip on me. I used heroin for a few months while living in Thailand, because it was widely available, but for over 10 years I was addicted to the opiates I was prescribed for chronic pain. All the while I published books, entered a PhD program at UC Berkeley, traveled the world, and taught elementary, middle, and high school. Opiate addiction is insidious.
Someone in this thread made a comment about not being a "typical addict." I understand what they meant by that, because I am aware of what the conceptions and stereotypes are of drug addicts. But that term is completely hollow. Addiction doesn't give a fuck who you are. You don't get to dodge it because you are wealthy, or because you come from a certain culture. It doesn't elude you just because you assume that you don't know any addicts, or because people in your world pretend that they don't have the typical problems that everyone else has.
Michael_25: Come on, now. Do you genuinely think you are unique when it comes to becoming addicted to drugs? Your claims that you somehow stronger and have more "willpower" than "addicts" as you said, are 100% ridiculous. You're no less susceptible to become addicted than any one else. Period. The idea that you are different is a fantasy. It can take years of casual use to become addicted to heroin and other potent opiates. After 3 months of use, it's very premature to start your victory lap. Listen to the folks on this thread. And perhaps try being a bit more honest with yourself.
Addiction is ubiquitous. Don't be a fool. Nobody can claim that they are not a "typical addict" or that they are immune from addiction.
