Woke up at 6 a.m. but was too sleepy. I didn't want to end up like yesterday napping for 2 hours so I went back and waited until 6:40 a.m. Now I am a little bit in better shape than yesterday.
(10:14 a.m.) I think I just slept through the alarm. But according to the egg timer, I pressed it off and went back to sleep.
2:40 a.m. -- 6:40 a.m. Core sleep
9:00 a.m. -- 9:40 a.m. Slept through alarm. It is good thing that I woke up by myself.
