Z's That I Need

Ok ok, so it's pretty late, or early,
Too much to contemplate,
Its almost 5am oh well, I'll survive a day
Sleepless in hell
Just a few words to complete my set,
Why burn a calorie or break a sweat?
Neither have offended me, so they shall escape such tyranny
Well, it's been fun to end with this short rhyme,
I'll see when I bleed words next time.
