I enjoyed Ferriss' book- though clearly not written for someone who makes her living as a journalist! (He recommends a news "fast" where you strike up conversations by having your colleagues tell you what's important in the news.)
I do read- non-fiction before bed, but between that and nursing my son, I'm out before my head hits the pillow.
Reading, my weekly candelit bath (the ONLY time I get to relax while wet!), and soft music are my top faves. I used to rather enjoy more strenuous nighttime activities, but I'd trade almost anything for sleep these days!
