I was diagnosed with ADHD eleven or twelve years ago by three MDs and one PhD on different occasions. I had tried almost every medication and the one that worked the best for me was Adderall IR but my DONE practitioner kept insisting that I be given Adderall ER no matter how many times that I told her it didn't work for me. When I took the extended release it would help me five hours tops but then it would say in my system making me feel speedy for over twelve hours. When taking an ADHD medication I need it to work all day and then be done. Adderall ER did not do this. It was not helpful for me and because I complained, DONE cancelled my membership.
