When we have looked at the literature published so far—and I haven't looked at the literature that has just come out on sleep and anxiety—the evidence we have seen would be moderate for certain conditions and weak for others. Over time, I think part of the challenge is going to be selecting what patients you're prescribing these drugs for. If somebody has anxiety and also has bipolar disorder and possibly schizophrenia, you're going to see a huge difference from what you would see in somebody who just has anxiety.
The veteran population is quite interesting. From 2000 to 2005 I was looking after military personnel, and from 2012 to now—seven years—I've been looking after veterans. It's a completely different population from non-veterans in terms of the comorbidities and the challenges they've had being in theatre. They're a completely different group.
Part of the reason we wanted to separate the data collection is that things that might apply to the general public may be different. I still maintain what I shared earlier. I think the information isn't absolutely clear at the present time. The fog is lifting, and over time, we will have a better idea.
I think the dialogue between industry, which has been funding some of the projects, and the federal government will be quite different five years from now from what it is today, but it won't be any different if we don't learn the lessons from our mistakes in the past.
