Dear Dr. John Cannell,Our family ospoetath Dr. Beals-Becker has been treating my son with autism since he was about 2 & he is now 9. He has shown GREAT strides .He keeps up with grade level & for the most part does great. But, he still does have HUGE melt downs once he gets home (very occasional) a few melt downs have landed us in the ER due to him screaming himself into having chest pains. He takes 10,000 IU of vitamin D per day every morning He started at 1,000, then moved to 2,000 & then 5,000 & then just upped to 10,000.(over the 7 years of treatment) So, the question is Dr. Beals-Becker wanted me to contact you & ask you Dr. Cannell if this amount is enough or if we should up it again .Or should we split it into 2 5,000 doses. He does have some difficulty sleeping so we weren't sure about a later dose of vitamin D.THANK YOU for your time.Stacy Forsyth
