I get perhaps 5 hours of sleep a day. It seems to be enough.

Fitting stargazing into my life used to cause extreme fatigue... until I
started sleeping with earplugs. I use the foam plugs found at hardware
stores, but there are a lot of choices. Being sound insolated allows
undisturbed deeper sleep, so I require less of it.

I never try to sleep during the day without ear plugs anymore. And
often at night, too. I also find that I often sleep deeper and better
-- and therefore shorter -- when wearing ear plugs. I "discovered" this
years ago when napping in the afternoon in preparation for a night of
observing. They're great! Also good for airplanes and anywhere else
unfamiliar.
