By nature I'm a night owl, as I can actually sleep well after staying up all night long and feel rested afterwards. This is because at some point when the sun goes down and the moon rises I get a sudden burst of energy that prevents me from sleeping for a good 40 minutes after going to bed, and not being able to go back to bed if I'm ever woken up suddenly.
Unfortunatly, by schedule I'm on a morningbird schedule, something that I despise, and actually feel unwell and (on the rarest of occassions mind you) depressed in the morning.
