ADHD (inatentive type) 11 yr old girl

We just moved to NY. my daughter was diagnosed ADHD inattentive at age 4. She took ritalin for most of that time as well as trying some other meds and natural methods.
At 9 bipolar was added as the primary and she started on modafil (sp?). Now at 11 she's in middle school and the lack of executive functions are becoming increasingly problematic.

BTW there is good chance my husband and I are also ADHD.

When she is in my care (hard to control school and grandma's house) I watch her diet. She sees a dr for med mgmt and a therapist.

I would much rather find a way to cure her instead of treating the symptoms. So I'm looking for any advice or suggestions. I've spent a lot over the years on things that did not work.

I'm looking for some tips from people that are where I am, not just promoting another expensive treatment that doesn't work. Many of them offer a money back guarantee but when you have your hands full, who can find the time to return the cabinet full of treatments that did not work?

In the last 2 years ago I made a huge discovery in my own health. I was having digestive issues as well as sinus problems that were getting to be unbearable.

After a few years of Internet reading I solved my problem. After surgery and a small fortune in meds a homeopathic dr solved the problem with a tiny bottle he sent me to put a few drops under my tounge. I THINK it was called Naso heal.

It appears to have been candida. I cleaned my diet from most sugar, corn syrup, additives, processed food. Then I added some anitfunguals probiotics. I'm now working on MSG but it will take a while for me to learn more on getting rid of these.
My question...

Does anyone know of a connection between candida and ADHD. Should I put her on the anti fungals (capric oil, GSE, psylumium (sp) and bennonite)? Has any one tried this with any success?

a new school year is about to begin. While I would prefer to not to use stimulants again, it's a hard decision to make when I have to watch her struggle. She is very bright but can't keep track of assignments or focus on long tasks. She can test out way ahead in most subject but is more than a year below grade level in math.
Or can anyone suggest something else that I should try?
