I'm at three months! Everything's going great and I'm tapering off the pain medication (Norco), very gradually. My tapering-off schedule will have me drug-free in three more weeks.
I have to say the drugs have surprised me. I wouldn't have traded the "use your meds on schedule to keep ahead of the pain" mantra for any alternative, because it made all the difference for me. But I did develop physical dependence which was made obvious when I tapered too fast. The withdrawal from this drug is AWFUL. Although I didn't experience the whole list of possible symptoms I did get anxiety, aching (knee and otherwise), insomnia, and this horrible thing called Restless Legs Syndrome which is its own kind of torture that is far worse than its name suggests. These symptoms are still there significantly, even with the very gradual tapering I'm doing.
Consequently I joined another forum that's just for hydrocodone withdrawal. As you'd expect it's so helpful to read others' experiences. When I first started experiencing the mental symptoms (anxiety and other stuff) I thought I was falling apart because I hadn't seen any similar experiences on this forum, although I'm seeing quite a few mentions in the last couple weeks. Unfortunately my various caretakers didn't give me any warnings about withdrawal either; they seemed happy to constantly issue me more prescriptions. So I had a rough 24 hours before I put it together than my incipient insanity was my body's flailing reaction to losing its access to a powerful drug.
It's possible that what has happened to me is uncommon and yet I'm putting it in here to keep my story complete. But my GP, who's working with me on the withdrawal, says that physical dependence can take as little as four weeks to develop and he sees this constantly. Again, I do wish the surgeon's office that gave me prescriptions would have been much more up front about what I was going to experience. Again, it wouldn't have changed my use of it during the first few recovery weeks. It just would have saved me a scare.
