We started difficult child on a trial of 5 mg of Focalin XR a week ago. Its hard to know if it is helping because of the time of year (excitement of Christmas, time off from school, visitors staying with us, etc.). It doesnt seem like it is working. What we have seen for sure is: 1) stomach aches, 2) loss of appetite, 3) more moody/emotional, 4) wound up at night and not able to settle down or go to sleep until about 2 hrs.+ later than usual. What I am wondering is should we keep going with it for the full duration (14 days) and then meet with his pediatrician, or should we call now and talk about it? It probably would have been a more accurate trial to start when he was back in school and on a normal schedule but I wanted to be able to watch for the side effects.
