I think we could each spend two hours answering that question. I think what might work is if I try and then turn it over to Dr. Nevin.
One of the things in the U.S. military that we've seen since 9/11 is that there are many programs trying to do early identification of post-traumatic stress disorder, traumatic brain injury and other psychological consequences of war. People get worried about their careers. We have not done—and on our part, this is a pity, in my opinion—a systematic screening for mefloquine as well.
I think it is important that you screen for all of those, as well as depression, which runs hand in hand with PTSD and isn't quite the same thing—also, of course, they're often comorbid with substance abuse—but by doing it in such a way that the service member honestly believes it will not impact their career. After they're off active duty, it's usually easier. When they're on active duty, they often are very determined, because they're so proud of their service and they really want to hold onto it.
