Hi,

     I am a Registered Sleep Tech, I was curious as to whether your son has any difficulty sleeping at night?  Snoring, Difficulty going to sleep, sleeping in strange positions, getting more and more wound up until he just kinda passes out to sleep?  Many teachers, parents and even many doctors are not aware that a sleep disorder can cause the same symptoms as ADHD.  The real problem is when children with a sleep disorder are put on medications for ADHD which are uppers it causes changes in their sleep (mainly Insomnia) causing less sleep which actually can make the problem with hyper activity worse.  Children that are sleepy, unlike adults, typically are more hyper have impulse control problems, can act out, and have difficulty concentrating when they are sleep deprived.  This can be due to a sleep disorder such as Sleep apnea (in kids typically caused by large tonsils and/or adnoids) or not getting enough sleep due to not enough sleep (about 10-11 hours for a child of 6) or due to poor sleep hygiene.  Just a thought, I hope you find a solution, I had a similiar problem with my daughter she is now 8.

Maybe he needs to try another medication.
