I've started DST in my own personal time zone this week, sort of. I've been alternating getting up at 5am and 6:30am -- I wake up easily at both times. They're 90 minutes apart, which is the length of the average sleep cycle (according to experts). On one of my 5am days, I felt tired as soon as I got to work. I haven't felt like that in a long time. I'm guessing I really do need to sleep for about 8 hours.

I think I'll be getting to bed by 10:15pm, and I'll let myself sleep until 6:30am tomorrow.
