Is it normal for my son to be taking 54mg of Concerta and him only weighing 50 pounds? Thats rediculous !!!!! He is "zoning" out everytime the med. releases whatever it is and where is it that it says its safe to give him or other kids this stuff like concerta...... show me some scientific studies showing he's going to be normal at the age of 18......... 25....40 !!!!!!!!!!!!
