Dark circles

If I don't start getting some proper sleep I might fall on my face. Lately, I can't seem to get to sleep before two o'clock in the morning. I don't know why but it's happening. I guess I just have to set up a doctor's appointment if it doesn't subside in a couple of days. By tomorrow I'll probably see the beginning of the dark circles under my eyes. Good health relies on a good night sleep my dad always said and I truly believe in this.
