So I guess it would be better to call this Biphasic sleep since there are just two phases. I felt really tired on day three and hit the hay a bit early. I was trying to nap for 20 minutes and sleep for 6 hours previously but my body needed more. I napped twenty and slept seven on day 3 and day 4 and feel much better now. I have trouble getting up from the nap still and get groggy around 4pm on my BART ride home but I am digging it thus far and will continue it next week. I am not sure what the weekend holds but I will try to maintain the naps. I will keep you posted.
