I can survive almost a full working week on 5-6 hours a night, but will need a long sleep-in on the weekend to recover. This isn't ideal and not what I aim for, just what I've noticed. Up until my late 20's / early 30's I'd get headaches and be a grump the very next day on less than 6 hours of sleep. I'm glad I'm past that, so I'm not immediately ruined by one bad night, but still need the eternal discipline for maintaining a routine for long term health.
