Woke up at 5:30 and didn't feel sleepy during the morning routine (run, workout, cook and eat breakfast), because I went to bed 22:30 last night. I guess, going to bed after sunset and waking up just after sunrise is the most comfortable condition. However, while my reading, I felt a little bit sleepy. This wasn't ideal, but I am sure I am heading to the right direction. I hope this will continue to improve.
