>>I've learned, over time, to take 5 to 15 minute naps. May have to do something with acupuncture - the first sessions I had back in nineties have taught my body how to relax and breathe deep, which somehow started happening during these naps. And I don't do that every day, either - sometimes a week passes without one, sometimes it gets as bad as three times in the same afternoon/evening. May have to do with my pressure getting low and me becoming sensitive to weather in the last decade or so. Rainy day does make me sleepy.

>>As a rule, after such a nap I'm fresh and operational for another four hours or more.

They can call it whatever they want, as long as it works :).
> I sometimes drop off in the bone-orchard (graveyard) where I have my lunch. In fact, last week some concerned passers-by came up to me with "Excuse me ... Are you all right?". I had to begrudgingly and reluctantly climb out of my somnalence to assure them I was.
Maybe you looked a bit pale? Maybe you did have some strange looking marks on your neck?
