I want to jump in and talk about, coming back to your point, informed consent. I don't know whether that 5% is really informed. If you look at the Peace Corps, they traditionally have been offered their choice of medications, and more recently they're supposed to be warned about the side effects of mefloquine. But if you ask the average Peace Corps volunteer, they say they never really got true informed consent. I took mefloquine in Somalia. I did not know then what I know now. If I had known it then, I would never have taken it, even though likely I would have been court-martialled or at least restricted from deployment for not taking it.
I think one of the things that happened in the U.S. is there has been enough press, especially around, say, Staff Sergeant Bales, that people are really sensitive to not wanting.... There's also all the anecdotal information. It's widely known that the unit who took mefloquine on Monday would all have bad dreams and nightmares at night. It's not a secret. What I don't know, again, is with your 5% what are the reasons for choosing that?
