the usefulness of mental medicine is quite a controversy issue, even in academic cycles, some consider it useful and practical way of getting rid of insomnia and depression but others insist that changing psychological pattern is the only fundamental method to solve those problems, for even if you get recovery from medical treatment, you would still get into those psychological snare for your ways of thinking and dealing with the world has not been changed. In my opinion, having some mental medicine in the treating process is OK, it indeed will help you suffer less and the psychological depend on medicine will give you positive hypnosis when you go to bed, for if you deeply trust in your drugs and believe you could sleep, your body and brain will adjust to the state just as what you desire and believe (that is what positive hypnosis means). However, the more important task you should do is to change you psychological pattern.
