It really depends on whether I'm on vacation or not. I've noticed I'm much more likely to appreciate the wee hours of the morning when I don't have to rush off anywhere. Especially so on an island vacation.
As for coffee I've never drank a cup in my life.
Based upon my observations of some people who behave like Jekyll & Hyde depending on whether they've had a cup or not....etc
I'm glad I avoided that addiction. :)
