Heather,
DS1 takes Focalin XR. He took 5 mg for 7 days then we increased to 10 for the rest of the month. Saw NO change at 5 and only a tiny change at 10. 15 seems OK, he has been on that for a month now. I can see a real difference when he is at school. He has lost his "happy" but hopefully that will come back. My sister's kids are on concerta and she said it took a few months to see DN happy again. Luckily, he is still eating well and sleeping reasonably well. He was on Concerta 18mg for a week and didn't go to bed before midnight once that week. Now he is in bed by about 8:30 and sleeps until about 7.
Good luck! We go back to the dev ped next week so it will be interesting what he has to say. This is the first visit since we started the meds.
