difficult child definately has ADHD. The ODD seems to have quietly, slowly gotten better. Still very stubborn. In the past two years he has tried Concerta, Focalin, Adderall and now Vyvanse. ALL put him in an extremely bad, angry, scary mood. So angry he is scared. He is taking 50mg's of Zoloft. (is that a lot to start?) Dr. last year gave some samples of Strattera and wanted him to take that for anxiety. We did not. The reason I put of Strattera is because the others are quick in quick out. It is easier to see how he does in just one day. Now I guess we need to go with Strattera. He doesn't do well on any stimulant. Does anyone know of a different ADHD medication that may work? One that is quick in, quick out?
