Hyperactivity/Hard Time Staying Focused

[Guest guest]

My 8 year old son was doing great in school for three months, but in

the last three weeks he has begun acting up in class. He has acted

out almost everyday during the week, been very distracted and hyper.

His yeast was moderately high in a recent test and his doctor

prescribed diflucan. He is gluten free, but does have dairy. I

stopped giving him cheese thinking maybe it was causing him to act

up. I have thought of anything and everything, but our schedule is

pretty much the same. He is such a picky eater. He is on a low dose

ADHD medicine, but I do not want to increase the dosage on it before

exhausting every other possibility. In the mornings at home he is

calm and for the most part cooperative, but it seems when he gets to

school he gets wound up. Any suggestions?
