Last night I began an experiment to change my sleep cycle. Most recently I have trained my body to go to sleep at 10:30pm and wake as early as 2am but more often between 4am and 6am.
My new sleep pattern will be to be at 8:30pm and wake at 12:30am, 1:30am or 2:30am. Last night was hard. I think I need coffee to make this work. Once it is stabilized and regular, I will have 4-8 hours of disturbance free productivity everyday!
