Surely a doctor would but be very easy going about the drug use. I just tell my psychiatrists me: "I swallowed them all". Him "What?" Me: "like down the throat".

Also it will be harder in Ireland to get stimulant medications but since you have a diagnosis then it sounds plausible. My first psychiatrist came and practised in Dublin so idrk. I'd say you have a good shot but psychosis treatment always comes first from my experience. Like if you have ADHD and your psychosis isn't getting better, forget about stimulant medications is what would be said.
