Now narcolepsy is really hard though because they're very tired during the day, they're sleepy during the day and it's managed mostly with medications. So we use medications to help them sleep better at night and to stay away during the day. But there are behavioral things you can do also by changing diet, exercise, having an actual nap schedule.

We try not using medications initially, and we use something called behavioral therapy for insomnia. This changes behaviors people do in bed, none of the tossing and turning.

There are some patients who just have insomnia and they've had it since they were a kid and we don't quite know why. So when we look at the cause, we definitely want to treat whatever else is going on, but insomnia often because it becomes its own diagnosis and that requires its own treatment.

There are other people that think that dreams actually do serve a purpose. But what that purpose is, we're not really sure. So some people believe that it actually does have some psychological representation of what's going on in the day, but there's no need to sit and really analyze it.

For some people they say, it's about wish fulfillment, it's about the things you are never able to do in your day you are actually fulfilling at night. There are other people who will say that it's actually telling you something.

So you have Sleep Stage One, Two, and then Three/Four. One is a little bit lighter stage of the quiet, non-REM sleep and then Three/Four is really deep, deep sleep. And what you want is, you actually want a number of - you want to go through all of these stages throughout the night.

Really if it's an hour or two after you've fallen asleep because you're in such a deep sleep at that point.
