you might think that most patients at sleep clinic are being treated for sleeplessness , commonly refered to insomnia. but it's not the case.

Even more dangerous is their failure to remain awake when driving or operating machinery

There are certain drugs that can help, and specialists suggest voluntary napping to decrease the frequency of such sleep attacks.
