My Ds just started taking this on Friday. I have noticed a slight change but not anything dramatic. He is not a whirlwind , just fidgety and restless, his main problem is his inattentiveness. I have noticed that he seems to be able to process instructions better and he seems to be a bit less impulsive but the change is not major. He is only on 10mg. This seems to be a pretty small dosage from what i have read on the internet. Am i expecting too much too quickly but I had thought the effect eas pretty immediate. Anyone elses Dc taking this and if so did you have results quickly. Also what dosage are they on? I am seeing the paed in another month or so and it seems a long time to be doing a trial. Would it be awful if I gave him 20mg to see if it made any difference? Apparantly the max dosage is 60mg a day ? Are 2 10mg tablets the same as 1 20mg tablet? Any experience welcome. TIA
