I can't sleep well and wake up at 3 or 4am these days. I was reading Sherlock comics so that I could go back to sleep, but I'm still awake. I threw in the towel, and decided to get up. I often read a English vocabulary book before going to bed. It helps me fall a sleep easily! I want to use my vocabulary book until it's worn out, but it looks still okay. Sherlock is my all-time favorite TV series:)
