I have been doing a Thing™ lately where I let the morning light wake me up instead of an alarm. Currently I am on an approximately two week streak of waking up at sunrise, and because the bedroom faces east, this means I have been waking up around 5:30 am. (Voluntarily!) I wish I were one of those people who could function on 5 or 6 hours of sleep, but alas, somewhat embarrassingly I need a full 8 to 9 in order to really feel rested.
