Michael Breus, PhD: So, one of the things that I have people have problems with is what I call the on-call response.And so this is just like a physician who is waiting for that phone call all night long, they are waking up all nightbecause they know they've got an early morning and they want to make sure that they don't miss their alarm.The easiest thing that people can do to try and thwart the on-call effect is basically to set your alarm, have somebody else, outside of either your home, or somebody within your home,to make sure that they will get you up at such-and-such at time. You can even have a wake up service if you're staying at a hoteland there are actually wakeup services that you can have call to your home again to make sure that you're getting up at the right specified time.Also remember meditation and relaxation before sleep will help with that. And if you wake up in the middle of the night, don't go for the alarm clock to look and see what time it is.Make sure you can't see the alarm clock. Spin it around. It will work. It's not going to break in the middle of the night.If you have to, set two alarm clocks, one on your cell phone, one on your regular alarm, and get yourself some sleep.
