Clonazepam worked like a charm for 15 years, then I couldn't have it anymore (doctor's choice, but my research convinced me that long-term benzo use has its risks). Mirtazapine is a tricyclic antidepressant which is sedating at very lose doses, but acts as an antidepressant and appetite stimulant at higher doses. I would say the effect is mild and inconsistent but I do think it helps. Seems to be a safe drug.
