Ask HN: Has anyone tried sleeping 3 nights a week?

Hello HNers, I find myself sometimes not sleeping the whole night, going to work in the morning, and just after getting home, I sleep for 10 hours and I'm fully refreshed. I never made this a habit, but I will maybe start doing this frequently and record the data about my health and my day to day mood/energy/etc. Maybe I would be sleeping 3 nights a week. What do you think HN ? Will you be interested in hearing back from me ? Have you done something similar ? Please do share
