Was it a slip?

[Iggo]

7. That's such a gray area.

When I got seventeen teeth yanked from my head in one day, I got twenty-something shots of numbing agent, and at least one shot of the stuff that makes the walls melt. I only raised my hand when I could feel something. That was the rules, and i stuck to them. As they were finishing up, the dentist says "I'm writing you a scrip for codeine" and even though I couldn't talk, I shook my head and went "unh-unh" and reached into my pocket and pulled out my black and gold multi-year key tag. He said "you sure?" and I nodded. I had to tough it out on ibuprofen. So I enjoyed the ride of the "special shot" knowing it was unasked for, but when it came to my choice, I chose non-narcotic pain meds. It's my position I didn't slip.

But knees and teeth are different. My advice is to be completely honest with your doctors. Tell them you're a recovering addict. And work out between you what's best for your recovery.
