I had severe insomnia. I was treated by two doctors, I drank everything and anything. And lo and behold, I went to the next doctor. He prescribed me Zoloft 100 mg. In the morning + Trazadone 50 mg. in the evening. After two weeks, a miracle happened, I started sleeping for 6-8 hours without waking up. My experience tells me that you have to be persistent. And even changing the psychiatrist brings results.
