Are bad sleeping habits driving us mad?

This is very "Chicken or Egg" -ish

Are bad sleeping habits causing mental illness or does mental illness lead to bad sleeping habits. It seems to me the reality is that they are two conditions that exist because of each other.

In other words, if you can't sleep you probably already are a little mad.

Short answer: Yes.

Who needs sleep when there is caffeine pills to take instead? :-)
