ft,
I had to get honest with my wife at the end of my run too, and I'm glad I did. I think that was the right thing to do. You seemed like a badfish.
It will never be enough. I certainly didn't start out taking 600-800 mgs/day, but that's where anyone with an addiction problem is headed by taking this narcotic. I didn't even get high for probably the last 2 years. It just kept me from getting sick. I was so tired of hoping the Dr's office would call to re-up my script, or borrowing from my buddy, or hitting the street. It's a terrible cycle of insanity. It consumed my life entirely.
It's difficult, but anything worth doing is. The only person that can keep you from seeking more oxy is you. You're through the worst of detox already. You don't ever have to feel the effects of detox again, if you choose to do so.
Be strong.
