Hi R.,
I can understand your concerns re the medication (even without the FDA notice). One of my nephews (son of my sister in law) had problems with ADHD, and they tried different things with him (he is in grade 9 now I think). What worked best for him was mainly two things: diet modifications (you can find books etc. on ADHD diet mods) including no sugar and certain other things like dyes and preservatives, and also they did a program which is what you may have heard of...WavePOINT biofeedback. This was very helpful to their son and he has continued to do well from all I have heard.
I don't know where it might be offered in the USA, but it was in Edmonton, Alberta, Canada that they did it (that is where they live - we are in the Bay Area near San Francisco) and I think it has been used successfully other places in Canada.
Do a Google search on WavePOINT ADHD and you might find something more - but if you put WavePOINT alone you'll get a whole lot of irrelevant results as that is the name used for other things (computer program, a production company and so forth).
You might ask your doctor to do some checking into it as they might have better access to current info on what's available and where to find it. Ask him/her about WavePOINT and perhaps they can help you find out more...and if they don't know about it yet, they should. :)
I hope things go well for you and you find some good help for your son - he is at a good age to intervene so he can enter his teen years without this problem affecting him so much.
Blessings,
