We all know how important (good) sleep is to be productive and happy. Nevertheless, with all of our work, family and friends commitments, most of us don't have enough time to sleep as much as we may wish to.
How many hours do you sleep on weekdays, weekends, generally? Do you drink coffee, tea, etc to keep you up when you don't have any other option but to stay awake (approaching deadline, etc)?
Is it enough for you? If not, how many hours would you wish to sleep instead?
