Legal Commentary

For the past week and a half, I have experienced a welcome period of productivity and synthesis on my book project.  It's not that I wasn't writing before, it's just that something has changed; there is an ease of thought and composition that wasn't there previously.  The project has turned into a tidal wave that I will happily ride until it dashes me on the beach (hopefully not the rocks!).  There is one change--I've begun to add a second "midnight" work period from midnight to around 3:30 a.m.  I have also started to write to music--Lady Gaga's "Bad Romance" seems to have some good karma for my keyboard.  I feel slightly ridiculous, but I suppose it makes sense...our four kids are in bed, the house is quiet, the phone doesn't ring, no one comes by to make home repairs or see if we want to convert to new religions. 

What are your writing routines?  At what times and in what spaces are you most productive?  Offices, home, or coffee shops?  Early in the morning, late at night or just whenever a spare moment comes along?  In music or silence?  In what moods?  In short, how are you generally at your most productive?
