You asked for it in your post! Give up, I do appreciate how hard it is wanting to do the very best for your child, I have been there, trust me ,actually 4 times! I am thinking that it may not hurt you or your son, to try the 'Natural " route, as you are obviouslyare not happy with what is happening at the moment what have you got to lose, and all we are concerned about is your Boy and making him feel better. I also think you are going in the right direction in your thoughts about sleep. So ,...I digress, how about as and when you can, you slowly, take him off all the Meds, with your Doctors help and input, My method is going to sound too easy and too simple but it wont hurt to try , he is 6 year old lets get him a lot of activity going, involve Dad ,sports, Games,Fun, outside acrtivities,wear him out so he is tired and wants to sleep, no talk about any form of illness, he is a healthy boy, if he crys and moans and acts out ,let him, dont feed into it , do not over -react to anything, It has been shown by experts that children do well when they take a Multiple Vitamin-mineral supplement with antioxidants, Vit BComplex and Vit C some parents have also found fish oil to be helpful. so you may want to consider that.I think you also need to re think how you are going about this issue , I believe you also think so . Good Luck let me know how he does.
