I'm a firm believer in naps being as good as a change (being as good as a rest), to the point that I've started to force the guys who work for me (I'm a humanitarian disaster-response coordinator) to take them at about 4pm. That way I can make them work 7am-midnight, 7 days a week for months and months and never once feel like maybe I should let them have a day off. (You can probably tell that I'm not that much of a humanitarian with my own people)

The 'headache-y nonsense' vs. 'best idea in the world' argument can probably be easily settled: as a new routine, it definitely does take some getting used to, but it gets more effective, and you start to need less and less for the same effect the more regularly that you do it. I used to need about 90mins or I would feel headache-y, but now I get 25mins every day, using Pzizz (natch) and can kick rrr for a long, long time.

As for being embarrassed about being asleep - I've always been jealous of old people who can just doze the afternoon away with their own 'mind like water': I always thought it was a wonderful thing and one of the main reasons that I am really, REALLY looking forward to being an old man. That, and the free license that old people have to dole out random vitriol at random young people. Personally, I can't wait.

Bah, kids these days... ;0)
