Typically, when I am suffering from a bout of WB, I redirect my attention elsewhere to things that inspire me as a writer. Translation: reading, reading, and more reading.
Mostly, I veer toward visually consuming all books that pertain to the current subject at hand. If I’m writing about a specific paranormal ability, such as clairvoyance, I’ll read everything I can get my hands on that deals with the subject. When subject-based research doesn’t help, I read for enjoyment instead. Frequently, reading a good book by a favorite author is enough to regenerate the creative juices and inspire me to start again.
When all else fails, I will work on another writing project until new ideas spring to mind. On the darkest of days, I consume copious amounts of coffee and stew in a dark corner. Thus is my life as a writer. :-)
