"my son is 8 and we just started this medication. started at 10mg and it was not enough so we went up to 20mg a few days later. his teacher noticed right away that things were better at school, but at home he was a nightmare. very emotional when coming off medicines in the afternoon. we got a booster of ritalin but now he is not sleeping. i am going to try concerta again to see if we can get rid of the emotional outbursts."
