"my son is 7 and was diagnosed a few months ago.  he started with the 27mg concerta and that didn&#039;t seem to help at all.  moved him to 36mg and he&#039;s doing a little better.  there are a few concerns though.  around 5:30, 6;00 in the evening he will have emotional meltdowns.  cries at the drop of a hat.  also i pretty much have to bribe him to eat and he has lost so much weight.  i am thinking about trying to switch to something else but not sure what to switch him to."
