It comes back on its own. Creativity that is. Being uncreative
  is suddenly boring again and then something you just HAVE to
  create pops up out of nowhere. But for now, enjoy your break and
  vegetate or whatever. Last week I watched 8 hrs straight of
  Doctor who Dalek episodes on a Sunday. Did nothing else. Told
  everybody to go away. I rarely watch tv. Like never. I'm always
  creating something or doing something for someone else. But that
  day? I wanted to do nothing. And so I did. After moping around
  for a few more days of plodding through life, doing what I had
  to do and no more... suddenly there was some creative thing that
  I HAD to do. Like "get out of my way to everybody cause this
  NEEDS to happen NOW" - and I got my groove back.
