I had a period in my life when I was going sleep in the morning and waking up at 3PM, sometimes sleeping for more than 12 hours. It wasn't devastating so much to my physical health as to my mental health. Sleeping too long is as bad as sleeping too short, not to mention going sleep in the morning for several days in a row. Sleeping properly really is essential for good physical and mental health, don't sacrifice it just to 'do more'.
