Thank you! I am freaking out about the stomach pain and throwing up but I did find something about withdrawal but not the symptoms. I will call the doctor today. Thanks! Any suggestions about what to try now? We have tried Adderall, which worked great but his heart rate was so high on it, Concerta didn't work all that great and abilify had too many side effects, like drowsiness and dry mouth and over eating. I'm thinking about going back and trying the Concerta. They want him to take a mood stabilizer also. The next one on their list is Risperidal.
