The no sleeping thing came up in a discussing in diving medicine. Something to do with the fact that you won't notice the onset of DCS symptoms if you are asleep, and you also don't offgas very well when you are sleeping.
I'm with you though...I've napped between dives and usually within a couple of hours after a night dive I'm usually out.
