So I'll go first, David, and then, as you suggest, I will ask Scott to make some comments. So, relative to the DOJ and the warning letter, etcetera, I think the first thing we have to acknowledge, and tried to outline this in the script, is that our customers, especially budget holders, are actually in a tough spot. And it's no secret that they are having a tough time. And so, if you are worried about getting through 2015 from a budgetary perspective, then the obvious thing to do is to look at your budgets and see where you might be able to make those budgets stretch. And that's really what we are seeing from pharmacy. I think mostly what we saw from the impact of the warning letter and the DOJ, is at the hospital level, was somebody who already had a predisposition to try to limit the access to EXPAREL, have a couple of additional regulatory tools, if you will, to try to institute that thought process. I would say that, as we've continued to move along and as the marketplace continues to evolve, we have started to see those things modify. And in fact, we've seen some places where restricted access was applied and where it hasn't worked to the satisfaction of care providers. And so we've seen people start to come back to EXPAREL, because they just couldn't achieve the same patient outcomes without it. On the surgeon side, on the anesthesiologist side, when the product is used appropriately, David, we have very little pushback, actually almost no pushback, from customers who treat patients. In fact, if there was no cost pressures, I think it would be pretty safe to say that virtually everybody would like to use EXPAREL virtually everywhere. But that's just not the real world. But we very rarely get pushback from people who treat patients. So I'll ask Scott to...
