The best resource I have found for ADHD medications is the book, New ADHD Medication Rules: Brain Science & Common Sense. by Dr. Charles Parker. If you don’t want to get the book. you can read the essentials at this link….. http://www.corepsych.com/add-adhd-medication-find-the-sides-of-the-therapeutic-window/
Or see his series of short Utube videos on adhd medication here….. http://www.corepsych.com/adhd-medication-tutorial/
another good overall link is this one….. https://www.additudemag.com/stimulant-medications-for-adhd/?utm_source=eletter&utm_medium=email&utm_campaign=treatment_march_2018&utm_content=030818
Hope this helps.
