On my Youtube channel I have several 20 minute talks on non-stimulant options for ADHD, including guanfacine https://www.youtube.com/watch?v=kp9bGbwk3BA and viloxazone https://www.youtube.com/watch?v=rhCnxj0q6uI

One of my preferred non-stimulant options is duloxetine/Cymbalta, which is not FDA approved for this use, but is often more tolerable than atomoxetine..
