I used to lose sleep. I can't sleep before four or five in the evening. I almost collapsed during that time. If you are an insomniac, you can probably understand that kind of suffering best.

Good night 27000 works very well. My relatives brought it back from Japan. I ate a few days ago, and it hasn't changed much. After about 10 days, I fell asleep unconsciously in bed. Later, I ate it for a while, and now I am completely awake until dawn ~ ~ ~ ~
