I used the last 20 minutes of my lunch to go lay down on a couch in a quiet room today, and I feel significantly refreshed. I'm considering doing this every day. This time I took a nap, but I could always bring a book. There's a timer in there, and that's nice because I can set it and 'forget'. I'm not as worn down as I usually am this time of day. Maybe I'll start taking my afternoon breaks in there too, if I can. What an improvement.
