For four of the past five days, I’ve stayed off email and text after 12:00 p.m.
On Friday, I tried an experiment. After dinner, I got online and browsed entertainment sites for an hour: Pinterest, Buzzfeed, et cetera. After watching a few episodes of Ripper Street, I went to bed at the normal time, and guess what? My mind was ping-ponging on all sorts of subjects without my consent. I tried to quiet it down but couldn’t. Sleep was fitful.
