As far as my experience of poor sleep in the Affiliated Hospital of Chengdu University of Traditional Chinese Medicine is concerned, none of them have been successful. About ten years ago, I went to see them, and the doctor dismissed these small problems of insomnia. Nothing has changed after taking the medicine. I hung up the expert number of 80 yuan this year, and I haven't changed a bit after taking the medicine. The most effective time for me to treat sleep was when an old Chinese doctor in the countryside took Chinese medicine for about a week, and basically it was very good in one year.
