i slept 12 hours out of 85 this week.. but then caught up just now so it's 25 out of 100 - or averaging 6 hours a night. i can't fit my sleep within a standard 24 hour period - in particular i find it hard sleeping twice within 18 hours. but on average i find i need to catch up to something fairly standard.
