I have had terrible insomnia (an hour a night) : / My Mirtazapine has conked out on me and it is sending me manic and agitated. It is really affecting my mental health now; I also have autism, so I obsess and get very depressed when no sleep. I have a telephone appointment with psychiatrist later this week. I really want to try low dose Quetiapine. The GP says she can't prescribe it. Psychiatrist can, I think. Any Quetiapiners out there tell me about it?
