Archetypes are what A5E calls subclasses.Yeah I was wondering what that was as well, I'll vote for it to find out
Have you tried online providers?I've had good results with the non-stimulant options, but that's very variable from person to person. My doctor randomly disappeared (seems to have taken a job with Kaiser without telling her patients), her office was replaced with a walk in clinic and they cut off my prescription and would not re-up when I scheduled an appointment and learned all this. Very weird.
I'm in the process of finding a new care provider now, but that's significantly more difficult with untreated ADHD.
Anyway, best of luck trying a new medication, hopefully you find a comfortable place.
