This subject makes me cry. I feel I could write another book on this one because I have ADD.
My oldest son has very severe ADHD which we knew early on this would be a problem and it still is. It's really hard and also sad. The poor kid struggles every day with everything.
He has been mostly on Ritilin for a million years seems like. Takes a while to get the right dosage adjusted. That's normal. Having to go back and forth a while getting the dosage right. And then, just when you think you've got it, the kid grows and weighs more and needs it adjusted all over again.
We've also tried Aderol and Stratera and other things too. Now we are on Medidate.
They all have some side effects one way or another: loss of appitite, upset stomach, headaches, different things. That's why it takes a while to find the right thing for each kid. He simply cannot function without it and Lord knows we have done everything in the world for him.
I guess you know now why there's an "edit" in almost 100% of my posts.
One thing that does help, is a sugarless diet.
And sometimes, you'll find that caffiene works backwards on an ADHD kid. If he needs to settle down and focus in a hurry and can't, he drinks a half a cup of coffee.
