Night owl by nature.
Somehow at my best late at night/early hours but since regaining employment, am usually up about 6 in the morning. Something about being up early appeals to me (ease into the day, watching the sun come up, knowing that I can do something useful, etc) but...
would still be a night owl given the chance.
(and my sleep pattern is knackered....constantly wake up between 3&4 oclock...though I nod off again... leaving me struggling through the rest of the day after dinner)
