Today, I have to use the computer to go on Italki. I had to once again log in and do it in the website verson (I use application on my Ipad).
I still keep the habit to wake up at 4:30. I have done it for a week now and today I got up at 5 because I slept later. I don't mind waking up early even though I have a slight headache in the morning and at night. However, I still wonder if it can effect on my health and my brain. Anyway, I will try to challenge myself for a week more before I decide to keep it or change it.
I sleep 6 hours at night and 30 minutes during the day.
Hope some one can share me their experience of practicing sleeping less.
