Today was the second day difficult child took Concerta. So far so good! I've noticed a change already. She's more mellow, and her impulsivity has decreased. Yay!! We've also had a lot fewer tantrums. psychiatrist and I went back and forth with pros and cons on Friday, and I agreed to give it a try. I was worried about adverse side effects as one of my nieces was on it and immediately developed tics and other undesirable reactions. I'm hoping things continue to go smoothly!
