There’s something strange going on about my life pattern at the moment. I cannot sleep until late at night, but I still wake up early in the morning. I want to change it back to normal, so I don’t take naps during day time no matter how tired I feel. However, as soon as the sun sets on the west, I don’t feel sleepy no more. I wonder if there is a fix to this. Maybe I can ask for some sleeping pills or maybe I can quit smoking. Or it’s just the weather.
