I couldn't exist without a nap. I have been napping since I worked as an au pair in France 49 years ago. I remember then thinking how civilised and wonderful it was - just half an hour after lunch. Now I burst out of bed in the morning and then sag in the afternoon. Have some zizzzzzes and burst awake raring to go again. I feel as though I am blessed with this incredible energy and always after a nap. You do what your body tells you to do and don't listen to those people who look down their nose and say "Oh, I never need a nap" as though it is something that inferior people do. All the high energy people I know have cat naps. And don't lie awake twiddling your thumbs either, or counting sheep. If your body doesn't need sleep at night, get up and do something positive! I've ironed at 3a.m. Yay, I say thumbs up to the cat nap. So Bea65, just do it. If it makes you feel better then that's a plus isn't it regardless of the time. I find I am sleeping more (I'm 69), but my general energy levels haven't subsided yet.
