Hi, Smileyfacedude. Though some here might be able to discuss it from the POV of their personal experiences, I think it's probably best to discuss this after a diagnosis. I don't know what they'll recommend, but there are non-stimulant drugs you can try first if you and your psych consider them appropriate. Alternatively, they may order some blood work and use that to make the call.

Welcome to the site, and best of luck with your upcoming evaluation.
