NEWBIE !! | ADHD Information

Hi everyone we are newly diagnosed and starting the battle of finding a good medication for my son who is 7 and in the 2nd grade. Doctor started him on Aderall not extended release and he can take up to 5 mg in the morning and if needed 2.5 at noon. We started with 2.5 in the morning only and while his teacher and myself noticed a  big difference with this the effects of it wearing off after lunch was very significant. He was very unfocused and off task after lunch and was more difficult to redirect than he ever was before med's even started so, we started a noon time 2.5 mg dose.  This has seemed to work other than making it hard for him to fall asleep in the evening but, that is getting better already. I thought we finally had it LOL I guess were not done adjusting because his teacher has noticed that in the morning we are starting to go back to how he was before meds he stays focused for the begining but, seems that after about 10am he is already hyper and off task again. I dont know what to do his behavioral doctor is really good but, he is difficult to get ahold of and we are doing most of our communicating through email.  I did express my concerns but have not heard back yet.  He has only been on Med's for a week and I dont know if I am trying to change them too fast also.  ANY advice is greatly appricatied cause I am at a loss of what to do next !!  maybe he would do better on an extended release
