My brain is an evil troll. Previously, especially before important events, he liked to reflect before sleep on the affairs of the messy, which often flowed into ordinary insomnia. Now I am very tired at work and in the evenings he does not stand out and falls asleep immediately. But see, at 5 o’clock in the morning from resting and waking me like "guard! Rise up! Let’s think of a little bit!" My brain and sleep are not compatible.
