Some of the drug companies now market, 'We have no hangover effect.' But they'll tell you, 'Give yourself the full eight hours of sleep' because they know if you wake up sooner, you're going to have the hangover effect.

They're consumers, and they're coming in for that. But the physician has the responsibility then of saying, 'You're a good candidate for that, you're not a good candidate, and this is what I recommend,' so I think it's going to be a double-edged sword.
