The plan was to sleep 3 hours and 15 minutes to test if I would feel more refreshed. So I set up my alarm and go to bed at 12 pm. I don’t know how but I didn’t hear any alarm ringing at 3:15 am, neither did my girlfriend. However, I woke up am by myself at 5:30 and was feeling refreshed and fit. I stood up and decided to skip the first nap today. This sleep gets 4 points straight.
Actually, its just one nap today. The core already took 5 hours and 30 minutes and I didn’t feel like I need much more sleep. I took it at 1:50 pm and it was refreshing. After this I didn’t felt tired until the late evening. I rated it with 4 points.
