Wow. My best-guess(/understanding, from popular media) is that, long-term, you need REM sleep. It's interesting that you (feel you) were able to short-circuit it, at least for a while. Anyway, the take-away I'm getting from your reply is that you are deliberately "sleep deprived", i.e., that you are driven, philosophically, to keep sleep to a physiological minimum. (Which tempts me, strongly, to view your sleep-deprivation (quote, unquote) as something akin to chronic drug use and/or anorexia.‡ ((‡ I might be way off-base here, of course.))
