I do not want to pass judgment on parents who medicate vs. those who don't. I have friends who medicate their kids. I have a child w/ ADHD and I don't medficate him because he also has other issues. I have been a teacher who had students that didn't learn without meds and I have seen students medicated to the point of zombiehood (when I was student teaching and volunteering) and it was very sad.
Here's what I have found with my own son, and I don't want to spark any anger, criticism or controversy. It is just my own experience with him.
He is 9 years old and our school has been pressuring us for 3 years now to put him on adhd meds. After tons of research, this year, we did some testing on him and found out he actually has a huge problem with yeast, heavy metal toxicity (mercury) and some other issues. He has been on Diflucan, which is an anti-fungal medication, many vitamins and a gluten free, casein free, mostly organic, free from preservative/color/additive, artificial flavors diet. He is doing SO MUCH BETTER. Our school finally has seen the light! We still have other issues and problems to tackle, but he is no longer the same child he was before. A have seen a major advance. Much of what I do is "natural," but the antifungal meds are meds, but I feel like they treat his medical problem...the reason he is unbalanced. Again, I'm not criticising children w/ ADHD. It's so easy to offend others when posting in black and white. If you heard my tone, you would hear me saying this in a very nice, kind, gentle way.

I just know my son is healthier and that if I gave my son adhd meds, I would just be masking the actual problem, rather than treating it.
The reason I post this here is just in case anyone is interested in more information. It took many years for me to find out about it and I know I would have liked to know about this a long time ago!
No parent wants to give their child meds. Nothing is easy in what I'm doing. It's tough, but not impossible. We all do the best we can though and my heart goes out to anyone who has a child with special needs, because I understand the struggle.
