How much do you sleep at night?
access_denied: As far as I am informed, the amount of sleep one needs varies from person to person.  I am no expert but I did read some stuff about it.  Also on the whole there is not done that much research about sleep.I did test it out for myself.  Without caffeine-intake my body regulates to a 7,5 hours sleep patern, no alarm-clock needed.  With caffeine (2 cups of coffee + a tea) and alcohol (2 beers or so) intake I need ~10 hours sleep per night.
