Hi Mark,
Thanks for posting that.
I've always had these very short naps during the day. I call them power naps. Usually only for about 15mins (I note the article said more like 45 to 60 mins) but they really help me get through my days. If I miss a power nap in the day then by dinner time I feel very fuzzy and my vertigo is bad. If I have my naps I do much better.
