I agree. I underslept for a few months. I didn't realize I had a headache all along until I made quality sleep my top priority. Now I go to bed at 9/10pm everyday. If I miss that window, it's much harder to fall asleep. Recovering from sleep deprivation also takes a long time, let's say, one week per night of work. the extra hours are not worth the overall loss of productivity and health.
