What do you find yourself doing on those sleepless nights?

Many nights I have found that Mr Sleep has forgot about my existence and has left me wide eyed and with extra hours of free time.
On those sleepless nights i usually find myself playing my guitar to accompany the orchestra of barking dogs and wild life outside my house.

Im curious, What do you find yourself doing on those sleepless nights.
Please don't write down "surf the internet" or "youtube" ;) I want to read interesting
stories.
