I've had hydrocodine when they've removed my wisdom teeth, and I didn't have problems at all. In fact, they gave me an entire perscription, and I enjoyed saving them for rainy days....
I've also used vicodin for pain killers, and they do wonders.
There's a drug called percecet (spelling?) I've taken that's completely numbed pain before, but that was for my back pain.
