Marjorie, Barb, et al........With all our talk re naps here's a page from about.com re naps...it says Chronic Fatigue Syndrome but it does relate to PWP et al who get tired in the afternoon....I copied a blurb from it. I read the page and took a nap and feel much better for having done so.....Joan Hartman http://chronicfatigue.about.com/health/chronicfatigue/library/weekly/aa08090 0a.htm?PM=68_1%2093_T "In addition to the stigma that may be associated with napping......... But research has shown that people who nap report no greater nocturnal sleep problems than non-nappers. In fact, napping reflects a natural biological rhythm and is a common feature of healthy adult sleep-wake behavior."
