Hi Dr. Smith,

I thought that you might have some insight on this. Yes, I've heard the point about the half-life of this drug, but that in itself doesn't explain it in a way that makes sense to me. Half-life means how long it stays in your system, right? I don't get what that has to do with needing to take it constantly. If anything, that would seem to me an opposite argument. And from what I've read, it takes the standard 30-60 minutes for the analgesic effect to kick in. So I still don't get it.
