Five Words

Experiencing these five words are glorious.  When I have it I am exhilarated.  When I don't have it I become confused.  When I don't have enough of it I suffer.  Sometimes I have it eight times a day; sometimes four times a day.  Believe it or not I have gone days without it.  Crazy I know.  I know many people who have it and have it more often then me.  They can have it all day long no matter what.  I just had it.  What power; what intoxication!.  I am soothed.  What is it?  A cool glass of water.
