Agreed. You aren't supposed to do anything in bed other than sleep (and, um, erm, one other adult activity).
Things like watching TV, eating, reading, anything you do in bed not having to do with sleeping trains your body into NOT sleeping in bed. Laying down to read is a no-no. You should do it sitting in a chair in a well-lit room.
