I’ve actually always been allowed to try what I wanted to try except for once when I wanted to try amitriptyline and the psychiatrist thought I was too high a suicide risk at that particular time for that particular med. But every other time - in hospital and in community mental health and in private mental health I’ve always been allowed to make suggestions and try them. I guess they figure you’re more likely to stick to taking them if you choose them. Maybe it’s a difference between countries too. My GPs have been the same with most meds too - if there are options they give you the choice as long as you can make an informed decision,
