I have been on hydrocodone for about 12 years for osteoarthritis in my knees.  I had one knee replacement five years ago.  The other knee just isn't to the point where it also needs surgery but I do experience enough pain that ice and Aleve don't always do the job.

Before my first replacement, I was taking two pills every four to six hours (and that's when the dosage was higher).  For the other knee I am currently taking no more than three pills a day, especially in the warmer months when I'm more active.

If I don't need pain relief, I don't take any pills because I'm not thinking about it.  A lot of times, I'll take Aleve and use ice, even when I probably should take a pill.  I guess I've been lucky or just don't have that kind of addictive behavior.
