My husband takes 2 to 4 naps a day. And when I say naps I'm talking 45 min. to an hour 1/2 each. Plus he sleeps like a baby all night; has never taken a sleeping pill. Tomorrow he's going to a dr. about his diabetes; I bet he has low thyroid (hypothyroidism). He isn't depressed; he just sits , eats and sleeps mostly. It is soooo strange living with someone who sleeps his life away. Can't wait to see what the dr. says. He's up now, yawning. Binkie
