This weekend I was unable to take a nap on Saturday but did notice being very sleepy on Saturday around 5pm. It seems like my body is in the groove of napping at that time and I am enjoying it. I stayed up til 1am and woke at 8am today feeling well so it seems I am on a 20 minute nap 7 hour sleep cycle. Per the 4 hour body book it says you can nap 20 and sleep six but so far I have not been able to do that without being fatigued. It may be due to me just needing more sleep in general as an active person. Today I ran for an hour through Tilden and napped for 20 minutes at 5pm and plan on getting seven hours tonight I will continue it this week and let you know how I feel. What I have noticed is a feeling of being "on" sort of more focused through out the day at certain times. Hopefully it will keep up.
